Police in the Bronx are looking for a man who they say attacked a teenager and stole her iPhone.

Investigators say the man seen in surveillance video followed the 17-year-old into a building on East 187th Street back on January 24.

He allegedly pushed her against a wall, dragged her down a flight of stairs, punched her and stole her iPhone.

The man is said to be in his early 20s, about 6'2" tall and weighing 160 pounds, with a slim build and black hair in corn rows.

He was last seen wearing a burgundy coat with a fur-trimmed hood.

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