State Police say 16 inmates and three prison staffers were aboard the bus when it turned onto its side at about 10:40 a.m. on its way to the Ulster Correctional facility.
The driver was reportedly pinned. Several of the inmates and the staffers suffered minor injuries, according to Dept. of Correction officials.
Injured prisoners were placed on stretchers. Staff and inmates were taken to Good Samaritan Hospital in Suffern. Video from SkyFoxHD showed several inmates wearing brown jumpsuits standing alongside the bus.
