18-year-old John Marine is charged with Riot, Criminal Mischief Under $1,000, and Disorderly Conduct by Obstructing Vehicular or Pedestrian Traffic.
It was Monday night when a disorderly crowd formed as the result of a party sponsored by "I'm Shmacked", which posts college party videos on social media.
On Thursday police released images of two criminal mischief suspects in the mob that damaged the roof of a Ford Mustang.
According to police, Marine saw his picture posted online and turned himself in to authorities.
The University of Delaware student was charged and released on $1,700 unsecured bond.
Investigators are still looking for the second suspect. Anyone with information is asked to contact Detective Greg E. Micolucci at (302) 366-7110 x132.
