The detainees at the Middlesex Jail in Cambridge were relocated Monday night and early Tuesday morning because of a water issue at the high-rise jail.
A spokesman for the Middlesex Sheriff's office said the evacuations were completed Tuesday morning. It was not immediately clear what caused the water issue and the spokesman would not say where the detainees were being relocated.
The Middlesex Jail is in a high-rise biulding in Cambridge and was built in 1971. It was originally built to hold 160 inmates, but it currently houses 340 to 400 pre-trial detainees, according to the Middlesex Sheriff's office website.
