Philadelphia police are searching for a masked man who they say harassed, chased and threatened several people near City Hall, including a woman whom he asked if she was “ready to die.” A warning circulating on social media included a photo of the masked man. The person who made the post said the man chased, cornered and threatened her while she was jogging. NBC Philadelphia obtained surveillance video of the incident. On Monday, Philadelphia Police Captain Jason Smith revealed a timeline of the incident, which took place on Wednesday, according to investigators. The suspect, who Smith said was wearing a “Chucky doll Halloween-style facemask,” was first spotted on 15th and Chestnut Streets that morning at 5:18 a.m. Police said he was running up to people trying to scare or antagonize them while holding a cellphone in his hand, indicating he was filming his actions. Police said the suspect then entered a Dunkin’ on 15th and Chestnut Streets at 5:20 a.m. but was refused service due to having the mask on. The suspect exited the store and was then spotted on the southwest corner of 15th Street and South Penn Square at 5:25 a.m. running up to more people in an attempt to scare them, according to investigators. At 5:28 a.m., the suspect then walked northbound on 15th Street, crossed the street and stopped at 15th and Market Streets on the sidewalk in front of Dilworth Plaza. He then began chasing after a man who was wearing a reflective vest, according to investigators. Then at 5:33 a.m., he began to chase after a woman who was jogging on the east side of 15th Street in an incident that was captured on video, police said. According to investigators, the suspect got in front of the woman while holding a phone and repeatedly asked her, “Are you ready to die?” The woman ran away, screaming for help and injured her leg in the process, police said. The suspect then went on the escalators at Suburban Station at 5:35 a.m. The suspect is described as a thin Black male between the ages of 16 and 20 and standing 5-foot-8. In addition to the mask, he was wearing all dark clothing, officials said. The man faces charges that include terroristic threats, harassment and simple assault. Some who work near 15th and Market Streets said they have also seen the masked man in the area. “He’s wearing all black with a mask, a scary mask, so you can’t see any of his identifying features. He just comes up and terrorizes people,” Kate Egan, who works in the area, said. A security guard who works nearby also shared a photo of the person near City Hall. Police also shared photos of the suspect without the doll mask on. In the images, he can be seen wearing a surgical mask and holding the doll mask in his hand. As far as police know, the man was not armed. Police are looking into whether the incidents were some sort of online prank, but said the behavior is no laughing matter. Investigators said only one person reported the masked suspect so far. They are asking others who may have interacted with him to come forward. People who work in the area said they hope police can put an end to the incidents. “No one wants to go to work in the morning, thinking that they might be harassed somewhere, and it could extend more than just harassment; they could be assaulted,” Egan said.
