Long Beach Police are trying to find a serial groper who has assaulted dozens of women in the past year while riding his bicycle.

Police believe the suspect has targeted at least 35 women since September 1 of last year. Victims' ages range from 12 to the mid-60s, according to City News Service. The suspect's MO is to ride up to or behind them on a bicycle and grope their breasts or buttocks as he speeds by.

Two grainy security cam videos released by the Long Beach Police Department show the suspect aimlessly riding his bike on the sidewalk. In one video, he is caught passing a woman and grabbing her in the shoulder area. Police believe that he may have access to multiple models of bicycles, according to the LA Times.

The suspect is described by witnesses as 5' 6" to 6' tall, and between 180 and 240 pounds with gray or black hair. The suspect's presumed age is between 25-50 years old, according to City News Service. Police have been knocking on doors in the area between 5th Street and Alamitos Avenue for any eyewitnesses.

Anyone with information on the suspect is urged to contact the Long Beach Police Department.
