OAKLAND, Calif. (KRON) — A man wielding a knife at Oakland International Airport caused an evacuation in Terminal 1 for several hours on Tuesday morning.

The shut down started at 5:45 a.m. The man was escorted into an ambulance around 9:40 a.m.

No one was allowed in or out, according to officials. Terminal 2 was unaffected.

The Alameda County Sheriff’s Office said the man was suicidal and threatening to harm himself, but not others. The incident was in the baggage claim area of the terminal before the checkpoint.

According to officials, deputies were able to deploy a taser after several hours of negotiations with the man.

A sergeant briefly struggled with the armed man, but the sergeant was able to wrestle the knife away from him, authorities said.

The man suffered a minor injury to his neck; no one else was injured.

Officials said just after 10:15 a.m. the man was on the way to the hospital for psychiatric help.
