A crew of looters smashed their way into a Brooklyn AT&T store — and then returned a short time later to grab more phones, police said Friday, as they released surveillance video of the burglary.

The suspects first struck the store on Metropolitan Avenue near Driggs Avenue in Williamsburg at around 2:25 a.m. June 1, using a sledgehammer to break the front door glass, cops said.

Once inside, the crew rifled through cardboard boxes and fled with armloads of phones, the footage shows.

Sometime between 11 that night and 4 a.m. the next day, they returned, this time smashing a glass window with a fire hydrant cap to get inside, cops said.

On both occasions, they left the store with multiple phones, according to police.

They were still on the loose Friday.
