Police say the suspects who robbed two Fordham University students may be responsible for three other similar robberies. 

They say the two men walk up to their victims, claim to have a gun or display a knife and demand the victim's cellphone and cash.

Students told police they were robbed by the two men on Feb. 25, March 9 and March 14.

The robberies took place on Southern Boulevard, Hughes Avenue, Hoffman Street and East 191 Street, according to police.

The suspects are described as being 18 to 22 years old, 5'10"-6'0" and weighing 170-190 pounds. Police say they were both last seen wearing a dark-colored hooded sweater and black sneakers.

Anyone with information is asked to call the NYPD's Crime Stoppers hotline at 1-800-577-TIPS.
