The daughter of Philadelphia Mayor Michael Nutter was assaulted during a high school track meet last week.
Olivia Nutter's mother, Lisa Nutter, told NBC10 Philadelphia that the 18-year-old was involved in an incident and is fine. She did not offer additional details.
Law enforcement sources told NBC10 Philadelphia that Nutter was attending a track meet at Morris E. Leeds Middle School in the East Mt. Airy neighborhood last Thursday evening when the assault occurred.
The mayor's daughter was walking towards a group of girls when one of them told Nutter to move, according to police. Moments later, police say, Nutter was assaulted.
Philadelphia police were called to the scene and the alleged assailant fled the field. Ciarra Ryan, 18, was arrested on Monday. She was charged with simple assault and recklessly endangering another person.
The motive in the attack is unknown. Officials also have not yet revealed whether Ryan were participating in the meet.
Nutter is a student at the city's prestigious Julia R. Masterman Middle and High School.
It is unclear whether Nutter has a security detail. NBC10 Philadelphia has reached out to the mayor's office for details.
