The '#AllWhiteAffair2015' ended in a large fight and shots fired outside a restaurant at the Monroeville Mall early Saturday morning, according to police.
According to police, the incident occurred about 1 a.m. during an event at Winghart's Whiskey & Burger Bar. Between 500 and 1,000 people attended.
During a news briefing Saturday afternoon, Monroeville Police Chief Douglas Cole said shots had been fired in the parking lot. No one was injured by the gunfire.
"We obviously do not know where the gunshots came from. We have positions based on shell casings that were found in the parking lot," said Cole. "At this point, we don't believe the gunshots were targeted at the police officers. We're not sure whether they were shot in the air or targeted another individual."
Cole said that after the gunfire, vehicles began speeding out of the parking lot and the crowd began to disperse.
A 25-year-old man was injured during the incident, but it is unclear how he was hurt. He was taken to Forbes Regional Hospital.
A 19-year-old woman was taken to UPMC East Hospital after suffering a medical emergency unrelated to the incident.
Officials said overcrowding was an issue at the restaurant, where college students dressed in all white for the "#AllWhiteAffair2015" event.
According to an online listing for the #AllWhiteAffair2015, students from Slippery Rock University, University of Pittsburgh, Indiana University of Pennsylvania and California University of Pennsylvania were bussed to the event.
Police arrested one person for disorderly conduct.
Cole said the venue for the event was originally supposed to be in White Oak, but was moved to Winghart's.
“Mall management was unaware that that was going to occur. Obviously, the Monroeville Police Department was unaware that that was going to occur,” said Cole.
The Monroeville Mall was closed at the time of Saturday’s incident. Police are looking into whether Winghart's violated any occupancy codes.
This is not the first time a gun or fight occurred at the mall in recent months.
In February, three people were injured when a teenager fired shots inside the mall’s Macy’s department store. The mall was also the site of a massive brawl that broke out while about 1,000 children and teenagers were present December 2014.
