Police want to track down a suspect who they said took advantage of a sleepy straphanger and a second man before he made off with a wallet and cellphone.

Authorities released photos of the suspect, described as a black man standing 6-feet-2-inches tall, weighing 160 pounds and black hair.

He was last seen wearing a blue baseball hat, black sneakers, blue jeans and a waist-length blue jacket while fleeing from a Brooklyn subway station. 

Investigators said the suspect eyed his first target while on the 2 train on Nov. 12 at around 3:30 a.m.

The 27-year-old victim was asleep when the suspect pilfered his wallet and made his way towards a second prospective target.

Cops said the second man noticed when the suspect snatched a Samsung cellphone from his pants pocket as the Manhattan-bound 2 train approached the Nostrand Avenue stop.

As soon as the train doors opened, the second victim chased the suspect out of the train car on the platform but was unable to catch up to him.

NYPD asks that anyone with information in regards to the suspect confidentially call the NYPD's Crime Stoppers Hotline at 800-577-TIPS or text their tips to 274637 (CRIMES) then enter TIP577.
