NEW YORK (CBSNewYork) — A knife-wielding robbery suspect who police said has targeted several chain restaurants in Queens has apparently struck again.

A suspect fitting the same description as previous crimes entered a Subway sandwich shop at 205 Northern Boulevard in Bayside around 9:30 p.m. Wednesday.

Police said he displayed a knife, removed about $400 in cash from the register and fled, possibly in a grey Honda.

He’s believed to be behind at least three similar robberies of a Carvel and two Dunkin Donuts in Queens last month, police said.

The suspect may also be responsible for a slew of robberies in Suffolk and Nassau counties since March, CBS2 reported.

The FBI is now assisting in the investigation, drawing up a profile of the suspect who is believed to be behind a total of 21 incidents, WCBS 880’s Mike Xirinachs reported.

So far, the suspect hasn’t hurt any of his victims, but authorities believe he will and they have labeled him desperate and dangerous, Xirinachs reported.

Police have released surveillance photos of the suspect from Wednesday’s incident.

He’s described by investigators as a black man, about 5’9″ tall with a medium build. He was wearing a grey hooded sweatshirt, dark jeans and boots.

Anyone with information is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
