Authorities are seeking the public’s help in identifying a suspect wanted in connection with seven bank robberies in Southern California since 2009, including one in Marina del Rey in November.

The suspect, dubbed the “Cooler Bandit,” is described as an Hispanic or bi-racial man between the ages of 16 and 25, 5-foot-5 to 6 feet in height, weighing between 110 and 155 pounds, having a thin build with black hair and brown eyes, according to the Federal Bureau of Investigation (FBI).

The Cooler Bandit is currently listed on the FBI’s local bank robbery website as one of two most active bank robbers in the region.

The suspect is known as the “Cooler Bandit” because he has been seen carrying a nylon-type cooler/lunch bag and water bottle during some of the robberies, an FBI spokeswoman said. As shown in bank surveillance photographs released to the media, the suspect has alternately worn sunglasses with orange lenses and clear glasses with a black outer rim.

The Cooler Bandit is suspected of robbing a Bank of America at 4754 Admiralty Way in Marina del Rey on Nov. 2, and six other Southern California banks, according to the FBI.

During the robberies, the Cooler Bandit allegedly enters the bank and approaches the teller with a note demanding money, the FBI spokeswoman said. The suspect usually leaves on foot, but was once seen in a stolen 1991 white, four-door Toyota Camry, according to authorities.

Although no weapon has been seen during the robberies, the suspect has allegedly threatened to kill victims who do not comply with his demands, the FBI spokeswoman said.

Anyone with information as to the identity or whereabouts of the Cooler Bandit is urged to contact the FBI in Los Angeles at (888) 226-8443, or dial 911 immediately.
