The FBI says the so-called "Geezer Bandit" has struck again in San Diego.

The FBI says a frail, elderly man gave a clerk a note demanding money and pulled a handgun Wednesday at San Diego National Bank. He left with an unspecified amount of cash.

FBI officials say they believe the man, who wore a white hooded sweat shirt and white ball cap, is the same man who has robbed five other banks in La Jolla, Rancho Santa Fe, San Diego and Santee since August.

Law enforcement officials are offering $16,000 in rewards for information that leads to his arrest and conviction.
