Long Beach police detectives are looking for a man with a lime-green bicycle who they think has groped at least four women since July around the Alamitos Beach and Bluff Heights neighborhoods.

Police have tentatively connected the man to four separate crimes between July 29 and and Dec. 27, according to a news release from the LBPD.

“In each of the incidents, the suspect approached the victims on a bicycle, groped them, then fled on the bicycle,” the LBPD said.

The department released the time and approximate location of each incident:

2:20 a.m. on July 29 in the 300 block of Molino Avenue

11:50 a.m. on Aug. 29 at Sixth Street and Alamitos Avenue

7:45 a.m. on Sept. 19 at Eighth Street and Junipero Avenue

8:10 a.m. on Dec. 27 in the 4000 block of E. Massachusetts Street

Police said the suspect is a Hispanic man in his 40s or 50s, between 5-foot-7 and 6-foot-2, 150 to 200 pounds with gray hair. He’s been seen riding a lime-green bicycle, authorities said.

In November, police asked for help finding a suspect in a similar string of incidents. They said that man had been riding around the Bluff Heights area where he’d groped at least three women between July and November.

Police urged anyone who has info about this man to contact Det. Adriana Jaurigui at 562-570-7372. The department said anyone who thinks she may have victimized should immediately call police dispatch at 562-435-6711.
