Six Flags' Halloween celebration "Fright fest" turned into a "Fight fest" after a massive fight allegedly involving as many as 200 kids broke out and resulted in multiple injuries at Six Flags America on Saturday night, according to social media posts and a woman who spoke with ABC7 News. Three people, including a 15-year-old who is in a medically induced coma, were confirmed to have suffered injuries, a fire department spokesman said.

At about 8:50 p.m., initial 911 calls began to be made by park visitors as the violence broke out, according to Washington Post. Multiple fights throughout the park, both inside and outside the gates, were reported by witnesses, who claimed there were not enough security personnel available to handle the crisis.

Occurring on the first night of the theme park's annual Fright Fest celebration, a 15-year-old boy fell to the ground after being punched twice. Since he struck his head on the concrete and suffered continued brain swelling, doctors are planning to remove a portion of the boy's skull for about a month to allow that brain space to expand and heal, family members said. For now, he is in a medically induced coma but in stable condition.

Two others were also injured in the altercation and had to be transported to the hospital, Prince George's County Fire Department stated. Among them was a 13-year-old girl who was taken to Children's Hospital for treatment, NBC Washington reported.

All other injuries, from missing teeth to bruises and cuts, were reported to be non-life-threatening, said Mark Brady, Prince George's County fire spokesman.

"As parents arrived on the scene of the Six Flags fights to search for their children, a horde of teenagers lined the park's perimeter on Central Avenue," Travelers reported. "Patrons were at the same time pouring out of Six Flags and filled the parking lot."

Parent Katrina Walker was picking up her son and his two friends from a birthday celebration at the park when she experienced the absolute chaos in the parking lot.

"It was panic, mayhem, chaos," said Walker. "Everyone was fearful...parents were very scared because we had no idea if our children were hurt or if they got in the middle of something."

"There were literally mobs of 20 to 30 kids per group and there was just constant fighting," said Margo Hodge, who was at the theme park with her husband. "There was a handful of security officers, but they had no control of the situation."

In another instance, Hodge also witnessed some teenagers remove their shirts and yell obscenities with the word "purge," including another person who was wielding a knife.

"It was absolutely horrific. There were huge massive groups that you could not even stop when they're running past you, you're holding to the side letting them go because there are so many kids," a mother of four, who asked not to be identified, told ABC7.

Meanwhile, authorities said they are investigating reports claiming that the teens used social media to plan the massive fight on Saturday.

"I hope nobody don't fight at six flags, but I already gotta feeling they are," posted one Twitter user.

However, none of the responsible culprits have been arrested, Maj. Major Raphael Grant, commander of the Regional Investigation Division said. "We haven't eliminated anything," Grant said, adding that the exact number of fights is still unknown.

While a Six Flags America spokesman initially released a statement saying, "reports of mass fighting or serious injuries are completely inaccurate. The safety of our guests is of top priority," they changed their stance by Sunday night.

"The safety and security of our guests is always our number one priority," said Six Flags America spokeswoman Havilah R. Ross in a statement, who described the violent brawl as an "isolated incident."

"Steps are being taken to increase security by working closely with local law enforcement; increasing the number of dedicated security personnel within the park, in the parking lot as well as along Central Avenue; and continuing to enforce a zero tolerance policy for anyone violating our published code of conduct," she added.

In the meantime, security and traffic enforcement have been increased for the remainder of the "Fright fest," which is scheduled to run every weekend through Nov. 2, according to Inquisitr.
