CHP locks down Oakland building after man spotted with gun

The California Highway Patrol on Wednesday morning placed a building in Oakland that houses Caltrans on lockdown after a state employee thought they saw a man in the parking lot with a gun.

The lockdown at 111 Grand Ave. in Oakland was lifted within the hour of the 6:40 a.m. call, CHP Officer Adib Zeid.

However, Zeid said that despite the sweep of the building, no suspect was ever found. 

Surveillance cameras showed that the man, whom the employee had ID'd, had left the area – but Zeid was not clear on whether he had actually been armed. 

The building houses the Caltrans District 4 office.

The lockdown was lifted just after 7:30 a.m.
