SAN DIEGO (CNS) - The FBI and San Diego police Friday sought the public's help in catching a would-be bank robber who attempted to hold up a Bank of America branch office in the College area.

The attempted robbery at 6801 El Cajon Blvd. occurred at about 12:10 p.m. Wednesday, according to FBI Special Agent Darrell Foxworth.

A man slid a demand note under the bullet-resistant glass of a teller's window, keeping his right hand on the note, Foxworth said.

The note threatened that the man had a weapon and the employee responded by backing away from the window. At that time, the would-be robber fled without any cash, Foxworth said.

Authorities described the would-be robber as black, in his mid- to late 20s, 5 feet 5 to 5 feet 8 inches tall, around 150 pounds, with an average build and low raspy voice.

Anyone with potential information in the case can call San Diego County Crime Stoppers at (888) 580-8477.
