Police are searching for a second suspect in an August robbery in Fort Greene.

The incident happened on Aug. 14 around 12:30 p.m. inside the Nevin Street subway station.

The NYPD says the suspect is believed to be between 17 and 18 years old, about 5’9” and around 170 pounds. They say at the time he was wearing a white shirt, black sweatpants and white sneakers.

Officials say he and 17-year-old Tajhion Harrigan went up to a 19-year-old man and demanded his belongings.

They say when the victim refused to hand those items over, one of the men threatened to stab him and then punched him in the face and took his phone. The other took the victim’s backpack, then both fled the scene.

Police say Harrigan was arrested around 9 p.m. on Aug. 14 and charged with robbery.

Anyone with information about the second suspect is asked to call police.
