OAKLAND — A transient is in jail after his arrest in connection with an apparent display of a replica firearm at a college campus, authorities said.

Around 10:10 a.m. Tuesday, dispatchers took a call reporting a person with a gun at Laney College, and officers were dispatched to the campus within minutes to search the area.

At 10:40 a.m., Lt. Gerald Verbeck, with the Alameda County Sheriff’s Office’s Peralta Community Colleges Service District, saw a man standing on the sidewalk on 7th Street near a college parking lot.

After seeing the man point a gun at passing vehicles, Verbeck, who was in uniform, approached him to try to draw his attention away from others, and gave him commands to surrender. The man ignored Verbeck, instead trying to hide the gun.

Moments later, Deputy Sonny Fahimi pulled up in a marked patrol car, and he and Verbeck began trying to coax the man to surrender, but he turned away after a few incoherent responses and started to walk toward the campus.

Concerned for campus safety, Verbeck suddenly ran at the man and tackled him to the ground, and both officers handcuffed him.

Officers learned the gun was a replica model of an assault pistol, covered with white camouflage paint splotches.

The man, identified as Man Bui, 55, was taken to a hospital for medical assessment and later arrested on suspicion of brandishing a weapon and obstructing a peace officer. He was in custody at Oakland’s Glenn Dyer jail on $10,000 bail and faces arraignment Wednesday at Dublin’s East County Hall of Justice.

Alameda County Sheriff’s Sgt. Ray Kelly credited Verbeck, a 25-year veteran officer and crisis-intervention unit leader, and Fahimi, who has served for more than a decade, with smart and brave choices.

“It took some courage to go in there not knowing whether it was a real or fake weapon,” Kelly said. “All they saw was a gun from a safe distance. It’s a good example of the training we do for the different situations our deputies are exposed to.”

Kelly also said the officers’ encounter in daylight was another key factor in preventing what could have been a tragic outcome.

“We’re thankful that it was daytime, because at night the situation could have been very different. There’s a misconception that officers want to escalate to lethal force, and that’s not true.”
