A silver-haired thief has robbed at least six homes in Queens — with the polo shirt-wearing perp pushing in A.C. units to break into residences, cops reported.

The suspect, who remains unidentified, was captured on home surveillance video ringing the doorbell of one residence multiple times and loitering on the front porch for over a minute, seemingly to make sure no one was home.

Six homes in the neighborhoods of Elmhurst and Jackson Heights have been targeted over the past month.

In each of the six incidences, the suspect either forced himself through a window or pushed in an A.C. unit to enter the residences, cops reported.

The first reported burglary took place on June 18 at 4:25 p.m. and the last burglary was reported on July 9 at 2:45 p.m., cops said.

The suspect stole cash and jewelry from each of the residences he broke into, police reported.

He was last seen wearing a blue polo shirt with pink horizontal stripes, blue pants, and white sneakers.
