NEW YORK -- Police say a teenage girl was sexually assaulted inside a Flushing, Queens park Thursday.

It happened around 3:30 p.m. at Kissena Park near Colden Street and Kalmia Avenue.

This sprawling park is popular among families and dogwalkers, and there is a middle school just steps away from the crime scene.

 According to police, a man approached a 13-year-old boy and a 13-year-old girl inside the park, pulled out a knife and forced them into a wooded area.

The man then allegedly stole both their phones before sexually assaulting the teenage girl.

Police say both teenagers were taken to a local hospital in stable condition.  

The suspect ran off on foot.

No photos of the suspect are available, but police say he is described as a man in his 20s who appeared to have dental braces on his teeth and a tattoo of a boar or a bull with red eyes on his chest. He is about 5 feet, 5 inches tall.
