Please see the following press release from the Chester County District Attorney. Pocopson Township will publish additional updates as they are received:

This afternoon, an inmate attempted to escape from the Chester County Prison. He was quickly apprehended due to a combination of security features and prison staff. All inmates are accounted for and there is no threat to the community. This is an active criminal investigation led by the Chester County Detectives in full cooperation with the Chester County Prison staff. Further updates will be provided in the future.

NOTE: As the subject never made it outside of the prison, there was no siren activation required.
