OAKLAND — A man wearing security guard attire robbed a Montclair bank Monday morning, the second time since November the suspect has targeted a bank in the neighborhood, police said.

Authorities believe the same man robbed an Alameda bank last month.

Police said the man, who was partially masked, entered the Bank of the West, 2023 Mountain Blvd., about 10:26 a.m. Monday, simulated a gun and demanded money from a teller he also threatened.

After getting an undisclosed amount of cash, some of which for some reason fell to the floor, the man walked out of the bank and possibly got into a waiting car. No one was hurt.

He was gone from the area by the time police arrived.

The robber is described as black, 30 to 35 years old, at least 6 feet tall and about 200 pounds. He may have had a mustache.

He wore a dark jacket that had security symbols on it over a hooded sweatshirt as well as dark cargo pants.

Police believe the same man in similar security guard clothing robbed the Chase Bank, 2051 Mountain Blvd., on Nov. 19. In that robbery he threatened two tellers with a pistol.

He is also suspected of robbing a Citibank branch at 2420 Santa Clara Ave., in Alameda on Dec. 10, threatening several tellers with violence if they did not comply with his demands.

Oakland police and Crime Stoppers of Oakland are offering up to $5,000 for information leading to the robber’s arrest. Anyone with information may call Oakland police at 510-238-3326 or Crime Stoppers at 510-777-8572 or Alameda police at 510-337-8350..
