Calabasas Bank Robbed Twice in 3 Days : Crime: The FBI is studying whether one person is responsible in both holdups, in which armed man asked to make withdrawal and asked for $100 bills.

Twice this week a man has entered Southern California Savings, strode up to a teller, displayed a semiautomatic pistol and told the teller he wanted to make a withdrawal.

Twice this week the robber has gotten away.

Whether it was the same robber is one of the things the FBI is trying to determine.

If so, “he obviously feels comfortable in that bank,” noted FBI spokesman John Hoos.

Descriptions of the robber differed only slightly, Hoos said, including the fact that the first one was clean-shaven and the second appeared to have a mustache.

But investigators believe it could be the same culprit, because the technique was virtually identical in both cases, he said. In both holdups--the first about 3:45 p.m. Tuesday and the next about 1:30 p.m. Thursday--the robber entered the bank on Calabasas Road and showed a teller a pistol in his briefcase.

In the first robbery, he said: “I’d like to make a withdrawal please.” Then he told the teller: “Don’t forget the hundreds.”

The robber’s words on Thursday were similar, Hoos said--”I want to make a withdrawal” and “Do you have any hundreds?”

“In both cases he just exited the building and walked away,” Hoos said. “It was quick in, quick out.”

Robbers who target the same bank twice in three days are unusual, but far from unheard of, particularly in Los Angeles, Hoos said. “When you’re the bank robbery capital of the world, anything can happen.”
