Olivia Nutter, the daughter of Philadelphia Mayor Michael Nutter, was assaulted during a high school track meet last week.
Lisa Nutter, Olivia's mother, tells NBC10 the 18-year-old was involved in an incident and is fine. She did not offer additional details.
Law enforcement sources tell NBC10 Nutter was attending a track meet at a field along the 1100 block of E. Sedgwick Street last Thursday evening when the assault occurred.
The track is located on the property of Morris E. Leeds Middle School in East Mt. Airy.
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.
Court records allege 18-year-old Ciarra Ryan punched Nutter in the head and pulled her hair.
Philadelphia Police were called to the scene and Ryan fled the field, police say. The teen was arrested Monday along the 5900 block of North Broad Street.

Ryan has been charged with simple assault and recklessly endangering another person.
The motive in the attack is unknown. Officials also have not yet said whether Ryan was participating in the meet.
Nutter is a senior at the School District of Philadelphia's prestigious Julia R. Masterman Middle and High School. Located at 16th and Spring Garden Streets, the school earned a 98-percent on its most recent academic progress performance report.
The teen became well-known in 2007 after starring in a TV commercial stumping for her father during his first mayoral election. She was 12-years-old at the time.
It is unclear whether the teen has a security detail. NBC10 has reached out to the mayor's office for details.
