Police are looking for a pair they say are behind at least 15 cellphone robberies in the Bronx.

The teenagers are accused of going on a monthlong robbery spree, randomly targeting a total of 16 people in 15 separate snatching incidents.

Authorities believe this pair, caught on video, is behind a number of robberies taking place in the Grand Concourse and Morrisania neighborhoods.

According to police, one of their incidents involved a 51-year-old man on Dec. 6.

The video shows the victim walking along Grand Concourse and 166 Street. Two males are seen walking near him when one of them snatches the victim's iPhone before fleeing.

Officials say the suspects are ambushing their victims while they are walking or waiting for the bus.

They say it all started on Nov. 2 when they sneaked up on a 31-year-old man who was walking on 167 Street and Findlay Avenue and took his phone right from his hands. Police say the duo struck another person that same day, just a few blocks away.

It has also got physical for some of these victims. In another incident, a 33-year-old victim told police she was walking near 165 Street and Grand Concourse around 5:30 p.m. when a man punched her in the face and took off with her iPhone. The next day, police say a 27-year-old victim was pushed to the ground for her iPhone along 163rd Street and Grant Avenue, near the same area they struck the day before.

The pair they're after are described as being between 15 and 18 years old.

Authorities are warning locals to pay attention to their surroundings.

Anyone who recognizes the men in the video or have any information are asked to call police.
