A person wearing a clown mask and holding a knife chased a 16-year-old boy in the 96th Street-Lexington Avenue subway station on Wednesday, police said.

The clown was blocking the door of a northbound 6 train when the boy tried to exit at the station around 1:30 p.m., cops said. The boy pushed through and exited through the turnstile. When he looked behind him, he saw the clown chasing him and displaying a knife, cops said.

The boy fled the station with no injuries.

The person wearing the clown mask is unknown at this time.

This incident comes as creepy clown sightings and threats have been reported across the country. This is the first known sighting in New York City, one NYPD spokesman said.

Clown Facebook and Instagram accounts made threats to about 20 tristate schools, including three high schools in the Bronx, News 12 Bronx reported earlier this week. The NYPD deemed the threats not credible.
