PHILADELPHIA — A New Jersey woman allegedly tried to set a "thin blue line" flag on fire during a Pride parade shortly after noon on Sunday, according to Philadelphia police.

Police arrested 18-year-old Ryan Segin of Woodbine, New Jersey. She was charged with attempting to commit arson, causing or risking a catastrophe, recklessly endangering another person and related offenses.

Online records for the Philadelphia Department of Prisons list Segin as a 20-year-old male who was lodged at the Curran-Fromhold Correctional Facility. Officials said bail was set at $5,000 during a preliminary arraignment. Bail was posted and Segin was released Monday.

Police first said Segin tried to light an American flag. A "thin blue line" flag is a black-and-white American flag with a blue stripe in the middle. According to Thin Blue Line USA, the flag honors law enforcement officers and their sacrifices.

No one at Philly Pride answered the phone or responded to an email message requesting comment Monday afternoon.
