Berkeley police officers arrested a 35-year-old Oakland man Wednesday morning after an alert resident spotted him carrying a gun through the neighborhood, authorities said.

Leonard Jackson was walking at Eighth Street and Channing Way toward San Pablo Avenue when a concerned citizen saw him with the firearm and called 911 to report it, said Lt. Kevin Schofield, a Berkeley Police spokesman.

Officers responded immediately and spotted the man at Channing and San Pablo. Officers told Jackson to sit on the ground, and he complied.

“Officers could see a rifle barrel protruding from under a blanket in his lap,” Schofield said in a prepared statement. “The officers blocked traffic and created a safe zone to contact Jackson.”

Police ordered Jackson to put down the gun and “though he was mostly non-responsive, he complied.”

Police took Jackson into custody without further incident and confiscated the rifle, which had a large-capacity magazine. Schofield said Jackson also had a spare magazine with him when he was detained.

He was taken to Berkeley Jail on suspicion of several charges, including being a felon in possession of a firearm, possession of cocaine and probation violation.

Jackson is not yet listed in the Alameda County Inmate Locator system, so no further information was available.

Said Schofield: “The Berkeley Police Department is extremely appreciative that an alert community member called us and that we were able to resolve the situation quickly and without injury to anyone involved.”
