The Bristol County Sheriff’s office reports that “both units are calm” at the Dartmouth House of Correction following an incident there for which not much information has been released.

“The Bristol County Sheriff’s Office is taking steps to make the facility more suicide-resistent. Part of this process is moving inmates to different housing units. Friday morning, some inmates in one of the housing units did not want to move, leading to the current incident,” Bristol Sheriff spokesman Jonathan Darling announced in an email at 1:04 p.m. Friday.

Sheriff Paul Heroux will provide further information before 6 p.m., the office said later.

Many outlets speculated about what the “incident” looked like, but at 2:06 p.m., the Sheriff’s office tweeted that “Rumors of a ‘full blown prison riot’ are false. We will share more details when we can.”

Eleven minutes later, the office announced that “All staff are accounted for. There are no staff hostages, and there is no reason to believe that inmates have taken other inmates hostage.”

One of the units was determined to be “under control,” with “no injuries in the operation” by 4:11 p.m. and that the staff had begun working on an adjacent housing unit.”

A little more than an hour later, the office said “both units are calm” and that they had begun finalizing inmate movement to conclude today’s incident response.”

This is a developing story.
