Police are looking for five armed thugs wanted for pistol whipping a woman during a home invasion robbery in upper Manhattan.

Surveillance video shows the three lookout guys fleeing the building’s lobby and being trailed by the two hoods that pulled off the push-in robbery.

The coordinated burglary went down at 10:20 p.m. on Aug. 7 when one punk posed as a food delivery man at the Cooper Street building in Inwood.

Once inside, an accomplice pulled a gun and forced the woman into a bedroom where he whacked her with the firearm, sources said.

The thieves made off with cash, a cell phone and the victim’s purse and and fled from the building, cops said.
