SUNBURY - Two male students were arrested by city police Thursday after making threats on Facebook against the treatment school they attend.

Police charged Michael Lepley, 18, of Hummels Wharf, and a 16-year-old Trevorton male with a felony count of threatening to use weapons of mass destruction and a misdemeanor charge of terroristic threats following the incident at the Five Star Treatment School, Susquehanna Avenue and Packer Street.

Sunbury City Police Sgt. Christopher Blase said the threat was made on a Facebook page between 8 and 8:30 a.m. According to a press release, the alleged threat said two students intended to use explosives against the school.

"Officials of the Line Mountain School District discovered the threat online and informed Shikellamy School District, where the school is located,

about the situation," Blase said.

An Internet search shows the school is part of a special education program with the Central Susquehanna Intermediate Unit. It is part of a full-time program for students with behavioral and social-emotional needs.

Emergency crews were called to the scene at approximately 12:30 p.m., but did not clear the school immediately.

"Classes normally end for the day at 1 p.m.," Blase said. "After the students left, we cleared the school and brought in bomb-sniffing dogs to searched the premises."

No explosives were found at the school and police took the two students in custody.

The investigation into the threat is continuing, but city police Chief Stephen Mazzeo reported in the press release there is no longer a credible threat to the public.

Lepley was arraigned before Magisterial District Judge Benjamin Apfelbaum and placed in Northumberland County Prison on $10,000 bail. The Trevorton teen was placed in county detention by juvenile probation officers.

Assisting police, the school and the districts in the investigation were members of the Zerbe Township Police Department, Pennsylvania State Police, K-9 units from Sunbury Police, the Lancaster County Sheriff's Office and Union County Sheriff's office.
