Would-be crimefighter shot in scuffle

A bystander was shot when he chased down three criminals who grabbed $2,000 from a grocery cash register Saturday night in Queens, police said.

The would-be crimefighter was inside the Bonoful Grocery at 2911 36th Ave. in Astoria at about 8:30 p.m. when one of the suspects displayed a gun, said cops.

The crooks grabbed the money and ran — and the good Samaritan, a 30-year-old man who was not a store employee, chased after them.

After a brief scuffle, one of the suspects shot the man in the leg, said police.

The wounded man was taken to Elmhurst Hospital and reported in stable condition.

The three suspects were last seen in a burgundy minivan driving north on 29th St., said cops.

At least one of the robbery suspects displayed what looked like a police badge, said a police source.

Anyone with information about the crime can call the NYPD Crimestoppers program at 1-800-577-TIPS.
