The Federal Bureau of Investigation is offering a $5,000 reward for any information that could lead to the arrest of the so-called "Droopy Face Bandit." The suspect is believed to be responsible for 10 robberies since 2007 within San Francisco, officials said.
The suspect, who has yet to be identified, uses a note to demand money and is considered to be armed and dangerous, according to the FBI.
The areas that seem to be his preference of target are predominantly Asian neighborhoods like Chinatown and the Clement Street area.
Anyone with information is asked to contact the San Francisco FBI office at 415-553-7400.
