A group of teens has been robbing and assaulting subway riders in Queens, police say.
Each of the victims in the three cases police are investigating was riding the J train along Jamaica Avenue when they were targeted.
In the early morning of Jan. 9, a 22-year-old man was punched in the face, but the suspects couldn't find anything to take from him, police said.
A woman had her iPhone 5 stolen on Jan. 12, and another 26-year-old woman had her iPhone 4S stolen on Jan. 16. Neither of the women were hurt.
Anyone with information is asked to contact Crime Stoppers at 800-577-TIPS.
