Police are urging members of the public not to approach a Nottinghamshire man who is on the run from Sudbury prison in Derbyshire.
Shawn Anthony Khera, 27, absconded from the prison overnight on Saturday into Sunday.
He was serving a four-year sentence for conspiracy to supply crack cocaine and conspiracy to possess cocaine with intent to supply. The sentence was handed down at Nottingham Crown Court in December 2015.
Khera is described as white with short brown hair and of medium build.
He has connections to the Carlton area of Nottingham.
A Derbyshire police spokesman said: "Anyone who sees Khera should not approach him but should call 101, quoting incident number 186/22/05/16. Alternatively they can call Crimestoppers anonymously on 0800 555 111."
