Even Mayor de Blasio can’t escape the city’s crime — a brazen crook stole pricy computers right out from under the noses of his staff, sources said.

The thief ripped off 29 laptops from a storage closet in a city office at 100 Gold St. in lower Manhattan, according to the sources.

The heist, which was first noticed during an inventory Wednesday at the Information Systems Management division of the Mayor’s Office, left probers wondering why security wasn’t tighter.

“What a bunch of boobs,” one law-enforcement source told The Post.

The swiped laptops included 24 Lenovo ThinkPads, which can average about $800 apiece, and five HP EliteBooks, which can go for about $1,000 each. All of the units were brand new, packed in boxes and locked in a storage area that was accessible only by key card, the sources said.

The computers were last seen during a previous inventory check in November by a member of the city’s IT Department, according to the sources. Only 25 employees have key cards for the storage area.

Investigators discovered three empty laptop boxes inside the storage area, and shortly afterward used the serial numbers to determine that two of the stolen laptops were put up for sale on eBay, the sources said.

Incredibly, There were no surveillance cameras near the area where the computers were stored, leaving police sources to wonder why.

“Security should know what they’re doing,” one source said.

City residents were astonished a municipal building does not have better security.

“That’s a government building. It should be as secure as the White House,” said Al Toure, 27. “[The theft] takes somebody with balls, though.”

The city-owned building near the Brooklyn Bridge is also home to the Department of Housing Preservation and Development.

A spokesperson for de Blasio would say only that the heist is under police investigation.
