Three recent knifepoint robberies on Flatlands and Utica avenues have area police and residents on edge.

Working on the theory that the three incidents are connected because their methods are so similar, cops are on the hunt for the two felons who took part in each crime before they rob anyone else.

Police said that the suspects, described only as black males, robbed two people on January 22 before going on a four day hiatus.

Their most recent victim was on January 26, officials said.

The first incident took place at 8:45 p.m. on January 22 when the two men pulled a knife on a 20-year-old male on Utica Avenue near Avenue K, robbing him of $73 in cash, some jewelry and his cell phone.

Fifteen minutes later, the thieves re-appeared, robbing a 28-year-old at knifepoint near the corner of Flatlands Avenue and East 49th Street, this time taking $90.

It’s believed that the thieves laid low for a few days before holding up a 13-year-old boy at the corner of Flatlands Avenue and Avenue L at 9 p.m. on January 26.

The thieves threatened the teen with a knife as they robbed him of his cell phone and music player, officials said.

No injuries had been reported in any of these crimes, officials said.

Cops are asking anyone with information regarding this incident to come forward.

At the same time, they are encouraging residents in Flatlands to be wary of their surroundings, especially if they’re walking where these robberies have taken place late at night.

Anyone with information regarding any of these heists is urged to come forward.

Calls can be made to the 63rd Precinct at (718) 258-4411. All calls will be kept confidential.
