Police are asking for the public’s help in identifying a suspect wanted in a series of violent crimes just over the Westchester border in the Bronx.

The NYPD says the man has been involved in five Bronx robberies in the last several days, all of them taking place around 1 a.m.

In each case, police say he displays a gun to store clerks and steals cash and merchandise.

Police are offering a $3,500 reward. Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS.
