Two guards were injured, including a guard who lost the tip of his finger, in an attack by an inmate at the state prison in Camp Hill last week, officials said.

Prison officials confirmed an “inmate-on-staff assault” that occurred on Saturday at the prison at 2500 Lisburn Road, resulting in two officers requiring hospital treatment. The officers were “treated and released” from the hospital, according to Deb Alvord, spokeswoman for the Camp Hill prison site.

Prison officials would not release any information about the medical injuries suffered by the guards, but a state police spokeswoman confirmed one guard had his fingertip bitten off.

A co-worker posted a photo of a bloodied finger, which appeared to be a pinky, on his Facebook page Sunday morning and said the incident happened in the “pill line,” which is where inmates line up to get doses of medication. The co-worker said it occurred during the 2 to 10 p.m. shift.

The incident was confined to the inmate and two guards, and the inmate was transferred to a “restricted unit” at another state prison, Alvord said. No information was provided about whether the inmate sustained any injuries in the incident.

Pennsylvania State Police are investigating the reported assault.

Alvord said she would not release any additional information beyond the prison’s initial short statement.

The Camp Hill prison has the highest population of any state prison with more than 3,300 inmates, according to the Department of Corrections monthly population totals. The prison was at nearly 90 percent of capacity in August, the most recent statistics available.

Statewide, the prison population was 45,832 in August.

The Camp Hill prison serves as the diagnostic and classification center for all male inmates entering the state prison system, according to the Department of Corrections website.

The facility has a diversionary treatment unit, mental health unit and a residential treatment unit.
