BROOKLYN, N.Y. - Police are on the lookout for three people who allegedly beat and robbed a teen in Brooklyn. 

Police say back on September 14, one suspected attacker approached an 18-year-old on East 54th Street and Church Avenue in East Flatbush, while the two others acted as lookouts.

He demanded the victim hand over his cellphone, but when he refused, police said he punched the teen multiple times with brass knuckles. 

Police say the other two men surrounded the victim, and he eventually gave up his phone.

The group ran off, and the victim was taken to the hospital and treated for facial pain and swelling. 

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-8477, or text CRIMES and then enter TIP577, or visit
