The NYPD's Special Victims Unit is investigating a possible sexual assault from this morning in Manhattan's Kips Bay neighborhood. A 21-year-old woman may have been followed into her apartment by a man who claimed to have found her wallet.

Sources tell DNAinfo, the assailant brought the victim's wallet, which contained an ID with her address on it, to her apartment on Lexington Avenue near East 26th Street at approximately 2:30 a.m. The victim told cops she left it at the McDonald's at 28th and Park Avenue South.

Police sources tell the Daily News the suspect said, "I have your wallet." According to the tabloid's source, "The woman checked her bag and saw that the wallet wasn't there. When she returned to the door, the man pushed his way inside and fondled her."

The NYPD press office could not provide any detailed information about the suspect, but a police source tells the News the suspect is "in his 30s and about 6-foot-3-inches tall with neck and chest tattoos. He has acne and was wearing blue jeans, a black leather jacket and a navy blue knit hat and gloves."

One local resident tells NY1, "It's really scary, you don't know who is going to be at your door and you just gotta be real careful, and really smart, and watch your back."
