Police are looking for a suspect in wave of robberies up and down Manhattan’s East Side.

The man is suspected in at least nine robberies since May 19 in which he simulates a firearm, said police, who released images of a suspect Friday. The suspect frequently uses a CitiBike to approach his victims and make his getaway, according to cops.

The man targeted his first victim on May 19 around 2:30 a.m. near E 24th St. and 2nd Ave., according to cops, when he rode up on a CitiBike and demanded a credit card from a 25-year-old man. In that incident, the suspect said he had a gun.

Around eight hours later at 10:15 a.m., the suspect barged in to a store on 2nd Ave. near 38th St. and flashed a gun before taking off with $200 from the register. He fled on a CitiBike northbound, according to cops.

The same man struck again the following Tuesday around 2:35 a.m. on Broadway and W. 86th St., but was unable to take anything from 52-year-old male victim.

On May 23, again around 2:05 a.m., the suspect intimated that he had a gun and threatened to shoot before he took $250 from a store register on Lexington Ave. near 85th St.

In the fifth incident on May 26, the suspect approached a 17-year-old on Ave. A and E. 3rd St. in the East Village on a CitiBike and demanded his cash. He rode away, but returned and grabbed $35 from the teen around 7:05 a.m.

Thirty minutes later and about 30 blocks away, the suspect again simulated a gun and took $200 from a store on 2nd Ave. near E. 35th St. That time, he fled on foot, according to cops.

Just after 8 a.m., the suspect struck again, demanding cash from a 28-year-old man walking on Lexington Ave. near E. 95th St before taking off on a CitiBike.

Two days later on May 28 at around 3:46 a.m., the suspect rode up to a store on 3rd Ave. and E. 106th St., displaying the outline of a firearm and making off with $300, cops said.

At 5:50 a.m. the same morning, he failed to grab cash from a store register on 3rd Ave. near 57th St.

Cops say they’re looking for a man about 6 feet, wearing a black hooded sweatshirt, a black hat, black sneakers, and blue pants.
