An 18-year-old woman has been charged with simple assault after an "altercation" last week with Mayor Nutter's daughter, Olivia.
Ciarra Ryan surrendered to Northwest Detectives on Monday, police said.
The incident followed a track meet at a stadium on East Sedgwick Street in East Mount Airy on April 18, police said.
According to court records, Ryan was accused of punching Olivia Nutter in the head and face and pulling her hair.
Few details were available Wednesday about what led to the incident - police said there had been "a verbal altercation."
