Nine teenagers who escaped from a juvenile prison facility Sunday night after a riot are being sought by authorities in the US state of Pennsylvania, according to police.

The Pennsylvania State Police and other law enforcement agencies "are looking for 9 juveniles who escaped from Abraxas Academy tonight around 8:00 PM," Pennsylvania State Police Trooper David Beohm stated on social media platform X.

“The escaped juveniles should be wearing gray pants or shorts and a gray shirt. Call 911 if you spot someone matching that description,” he said.

Beohm claimed that a perimeter had been set up around the juvenile prison center in Morgantown, southern Pennsylvania.

“This evening there was a riot at Abraxas Academy,” Caernarvon Township Police Department said in a separate statement on Sunday.

Authorities on the scene “have taken back control of the juvenile detention center,” it added.

The Abraxas facility offers “detention services” and a “residential treatment program (that) provides specialized care for delinquent male youth between the ages of 14 to 18,” according to its website.
