PHILADELPHIA, Pa. (WHP) — A creepy encounter in Pennsylvania is under investigation as Philadelphia police are searching for a masked man accused of chasing and threatening people while wearing a “Chucky” mask.

Philadelphia police said the man threatened and chased at least half a dozen people around City Hall. The encounters happened around 5:18 a.m. on Aug. 12 and reportedly even included asking one woman if she was “ready to die.”

The police said the person of interest is facing charges that include terroristic threatening, simple assault, and other offenses.

It is believed the masked man recorded the encounters, but it’s unclear if it was part of a social media trend.

He was last seen on camera running toward people around 5:25 a.m. near Penn Square.

So far, the police said only one person has spoken with the police about the reported encounter. Anyone with additional information is urged to contact the Philadelphia Police Department.
