A prisoner at the the Brandon Correctional Centre was hospitalized after an attack at the jail.
Police say that guards at the jail informed of the attack at around 11:40 p.m. Thursday night.
A man was found in a cell with non-life-threatening "significant upper-body injuries", which included lacerations or gashes. It's believed he was attacked by four to five other inmates, although a motive hasn't been determined.
No weapons were involved in the assault that happened in a subunit of the jail, although further details, such as a specific location of the beating, aren't available at this point.
No arrests have been made and the Brandon Police Service's Criminal Investigation Unit continues to investigate.
According to a provincial government website, the Brandon jail is primarily medium security. On Friday, a Manitoba Justice spokesperson said the capacity of the jail is 252 inmates but the current population stands at 317.
The spokesperson said an internal review into the assault is underway. However, the department wouldn't provide further details on the beating, citing the ongoing police matter.
