At least seven protesters outside the Democratic National Convention were arrested after jumping a security fence and are now facing federal charges.

Seven DNC protesters face federal charges, according to David Spunt of KYW-TV, who spoke with Philadelphia Police Commissioner Richard Ross.

With a helicopter overhead and still around a hundred protesters reported past midnight by Buzzfeed, things seemed to be dying down. There was even a group hug, Michaelle Bond of the Philadelphia Inquirer reported.

Lots of police on the other side of the fence. You can also hear the chopper overhead. pic.twitter.com/Yhuw7Azufv — Jim Dalrymple II (@JimDalrympleII) July 28, 2016
