For a brief moment there was panic along the Ben Franklin Parkway Thursday night as thousands gathered to celebrate the Fourth of July holiday.

Police say a crowd ran down the parkway during the fireworks show after hearing loud popping noises that many believed to be gunshots.

Investigators say someone fired a BB gun into the crowd. No one was injured in the incident and police were able to grab the gun so that no one else would panic.

Rumors of a shooting spread across social media sites but police say that they are not true. Some described the incident as a stampede.

No arrests have been made in the incident.

About 500,000 people flocked to the parkway for the annual birthday bash.
