Detectives say a Pennsylvania inmate being hauled off to solitary confinement grabbed a guard's stun gun and fired, injuring four correctional officers.

Authorities say Beaver County Jail guards had found two pills in the cell of 25-year-old Codie Dotterer on Jan. 7. While transporting him to solitary confinement, detectives say, Dotterer snatched a stun gun and fired.

Detectives say one guard was hit with its electric probes, two others were shocked by the wires leading to the probes, and a fourth was shocked because he was holding onto Dotterer's feet.

The Beaver County Times (http://bit.ly/1T8xEkb) reports that Dotterer faces a preliminary hearing Feb. 16 on aggravated assault and other charges.

Online court records don't list an attorney for him.

The pills found in his cell turned out to be Tylenol.
