In a brawl apparently instigated using social media, a thousand or more young teen black girls descended on Monroeville Mall outside Pittsburgh Friday night, resulting in the mall being closed as a massive brawl broke out. An investigation is ongoing, including via social media, although no arrests were reportedly made at the time.

Many of the teens used their phones to capture video of the events and that too is now making the rounds via social media.

Officers from several municipalities were called to the mall Friday evening after the fight broke out. Monroeville Police Chief K. Douglas Cole told Channel 11 News that there were about 1,000 children and teens in the mall when up to six different fights took place. Cole said at least two people were hospitalized with non-life-threatening injuries.

One Instagram user, in a comment on a video reposted from another account, said the fracas consisted of 6 fights, which were “all planned.”
