Take this for what it’s worth...

A member on BH said he saw on Twitter that supposedly he was wheeled into a corner where there were no cameras and 3 guys beat him with a slock and gouged out his eyes with a shiv.

Another poster said he heard the same thing.

A slock is a lock in a sock. Anything solid inside of a sock is a common prison weapon. Hard soap, canned goods, etc. have also been known to be used.
