Santa Rosa police Capt. John Cregan says officers used the video to track the 17-year-old shooter to a physical education classroom Tuesday.

Earlier, the gunman had argued with a 16-year-old boy and then shot him twice just outside Ridgway High School. The victim is in stable condition.

Cregan says the shooter blended into the nearest classroom as the attack triggered a lockdown for thousands of students at three schools.

He called it "disturbing" that the student went into a classroom and was "behaving normally."

Police say the gunman stored the handgun inside a backpack, which he handed off to someone in a vehicle before going into the classroom.

1:40 p.m.

Police say an argument between two students led to a shooting outside a Northern California high school, with one of them opening fire with a handgun before returning to class.

Santa Rosa police Capt. John Cregan said the 17-year-old gunman has been arrested on suspicion of attempted murder following the attack Tuesday on the sidewalk just outside Ridgway High School.

Cregan says a 16-year-old boy was shot twice and is in stable condition. The captain says the shooting was isolated and there's no indication that additional violence was planned.

Police previously said an accomplice was involved but now say that juvenile has been released.

Cregan says the shooter put the gun in a backpack and handed it off to someone else. It's unclear if that person knew a gun was inside, and the weapon hasn't been found.

12:10 p.m.

Police say a gunman and his accomplice have been arrested in connection with a shooting just outside a Northern California high school that wounded a teenager.

Santa Rosa police Sgt. Summer Gloeckner says detectives are interviewing the two following the shooting Tuesday on the sidewalk outside Ridgway High School. Police haven't yet identified a motive.

Police say the gunman was caught on the school campus. It wasn't immediately clear where the second suspect was arrested or what role he had in the attack.

A 17-year-old boy is in stable condition after being shot once in the abdomen.

Authorities are still searching for the shooter's handgun.

The shooting forced a lockdown at a sprawling complex that also includes Santa Rosa High School, Santa Rosa Junior College, school district offices and athletic fields. It has been lifted.

Authorities in Northern California have lifted lockdowns affecting two high schools and a community college after a shooting Tuesday morning wounded one person.

Santa Rosa Police posted on social media shortly after 11:30 a.m. that they conducted a thorough sweep of the three campuses and there is no evidence the weapon is on campus.

A potential suspect is in custody.

The shooting occurred near Ridgway High School and also affected Santa Rosa High School and Santa Rosa Junior College.

11:05 a.m.

Police say a potential suspect has been captured after a shooting near a high school in Northern California wounded one person.

Santa Rosa police Sgt. Summer Gloeckner says authorities are searching the Ridgway High School campus Tuesday for any other possible suspects.

Police said the shooting was originally reported on campus but are now saying it was close to the school.

TV footage from a helicopter showed a boy or man being led away in handcuffs while students were taken out of a building and searched.

Authorities say a male victim was shot once, reportedly in the abdomen, but his condition isn't immediately known.

Police tweeted that they're looking for the gunman's weapon. They previously said it was a handgun.

Officials have locked down the school as well as nearby Santa Rosa High School and Santa Rosa Junior College.

10 a.m.

Police say a shooting at a high school in Northern California has injured one person and set off a search for the suspect.

Santa Rosa police Sgt. Summer Gloeckner told the Press Democrat newspaper that it "doesn't appear to be an active shooter situation."

She says a male victim was injured and being treated at a hospital but didn't release more details about his condition.

Gloeckner says the shooting happened Tuesday morning on the campus of Ridgway High School in Santa Rosa, about 55 miles (89 kilometers) north of San Francisco.

Officials have locked down the school, as well as nearby Santa Rosa High School and the Santa Rosa Junior College.

School district officials couldn't immediately be reached.

WASHINGTON (AP) — Russia has moved some troops onto an airbase in Niger where a small number of U.S. forces remain, but Defense Secretary Lloyd Austin said he doesn't see it as a significant issue. Most American troops left that base in the nation's capital, Niamey, a U.S. official said.

The arrival of Russian trainers in the West African country about three weeks ago came in the wake of Niger’s decision to order out all U.S. troops. The order dealt a blow to U.S. military operations in the Sahel, a vast region south of the Sahara desert where groups linked to al-Qaida and the Islamic State group operate.

The Pentagon has said the U.S. troops will depart but has not provided a timeline.

When Russian troops arrived last month, it was unclear where they were staying. The Niamey base, Austin said late Thursday, is located at the capital city's Diori Hamani International Airport, and “the Russians are in a separate compound and don’t have access to U.S. forces or access to our equipment.”

He said the U.S. will continue to watch the situation but he doesn't see it as a significant force protection issue.

A U.S. official said the Russian forces are on the other side of the Niamey facility, known as Airbase 101, and that other international forces — such as the Germans and Italians — also reside. The official spoke on the condition of anonymity to discuss troop movements. It's unclear how many U.S. troops remain at the Niamey base.

The Russian presence on the base comes as tensions remain high between Washington and Moscow over the ongoing U.S. support for Ukraine's military.

About 1,000 U.S. troops are still in Niger, but the bulk of them moved to what's called Airbase 201 near Agadez, some 920 kilometers (550 miles) away from the capital, not long after mutinous soldiers ousted the country’s democratically elected president last July.

A few months later, the ruling junta asked French forces to leave and turned to the Russian mercenary group Wagner for security assistance.

In October, Washington officially designated the military takeover as a coup, which triggered U.S. laws restricting the military support and aid that it can provide to Niger. Since then, diplomatic efforts to restore ties with Niger have been unsuccessful.

Until recently, Washington considered Niger a key partner and ally in a region swept by coups in recent years, investing millions of dollars in the Agadez base, which has been critical to U.S. counterterrorism operations in the Sahel. The U.S. also has invested hundreds of millions of dollars in training Niger’s military since it began operations there in 2013.

The Pentagon also has said the U.S. will relocate most of the approximately 100 forces it has deployed in neighboring Chad for now. Chad is also considering whether to continue its security agreement with the U.S.

Maj. Gen. Pat Ryder, Pentagon press secretary, told reporters that the departure from Chad "is a temporary step as part of the ongoing review of our security cooperation, which will resume after Chad’s May 6th presidential election.”
