Investigators on Saturday released a surveillance image of a suspect in the theft of a woman’s cellphone in Bedford-Stuyvesant. The 26-year-old victim was at Fulton Street and Nostrand Avenue at around 8:45 a.m. on April 27 when a crook snatched the phone from her purse and ran off, said law-enforcement authorities. A surveillance camera at the Nostrand Avenue subway station captured pictures of the fleeing suspect.

A nerdy burglar broke into a Lower East Side computer and Web design business, stealing cash and vandalizing property, authorities said Saturday. The bespectacled thief slipped into the office on East Broadway near Allen Street at around 3 a.m. on May 16 and walked up to the second-floor offices, according to cops. The backpack-toting suspect then pocketed $50 and a pair of headphones before dumping a liquid on a laptop computer, police said.

A prowler wearing a baseball shirt took an iPad from a Financial District school, cops said Saturday.

Three tough gals beat and robbed a woman in a Lower East Side housing project, authorities said Saturday. The crooks trailed the 34-year-old victim into the building in the Baruch Houses on Columbia Street near East Houston Street at around 1:30 a.m. on May 8 and cornered her in an elevator, cops said. Once the door closed, the toughs set upon the woman and ripped off her earrings and bracelet, then dashed out of the building, police said. The victim declined medical attention.

A less-than-competent burglary suspect sawed his way through the ceiling of a Flushing loan office in an attempt to loot its safe — only to fail in his bid to unlock the strongbox, cops said Saturday. The burglar worked his way up to the third floor of the building on 39th Avenue near 138th Street at around 4 p.m. last Monday and cut a hole in the floor, police said. He dropped through the opening to the second floor of the Provident Loan Society and tried to bust open the safe, but left when he couldn’t get the door to budge, authorities said.
