The NYPD is looking for a man they say attacked a 16-year-old girl and her 2-year-old brother in Crown Heights last week. The man allegedly followed the siblings home, then punched the teen in the face and choked her.

Cops say the incident took place on Wednesday, May 3rd. At around 10:35 p.m., police say a man in his 30s followed the teen and her brother from the Franklin Avenue subway station into their apartment building near Franklin Avenue and Carroll Street. He then allegedly engaged the teen in conversation outside her apartment door before forcing himself into the apartment—cops say that's when he punched her in the face repeatedly and choked her before stealing her cellphone and a laptop from the apartment.

The man then fled the scene, according to police. The teen was transported to Kings County Hospital in serious but stable condition, where she was treated for lacerations. Cops say her brother was unharmed.

Chillingly, the Daily News reports that when the suspect followed his victim and her brother home, he offered to carry the toddler for her, but she refused. And when they arrived at her apartment, the News reports that the man first offered to put her little brother to sleep for her; she also refused. The suspect also allegedly asked to use their phone shortly before attacking the teen.

Cops say the suspect, pictured above, is in his 30s, 5'5" to 5'7"; last seen wearing a black baseball cap with the Superman logo, a black jacket with yellow piping on its arms and grey sweatpants.
