Police have warned people to stay away from a "dangerous" prisoner who escaped while receiving hospital treatment.

Omar Aslam (21), from Aston in Birmingham, overpowered a prison officer to flee on Saturday night while receiving treatment for tuberculosis at Leicester Royal Infirmary.

He is currently serving a seven-and-a-half-year sentence at Ashwell jail in Rutland for grievous bodily harm.

Detective Inspector Lee Hill said: "This man is dangerous and we need to recapture him as soon as possible. He also has an infectious disease and anyone seeing him should not approach him, but contact the police immediately."

Aslam is described as Asian, 6ft 3in and of slim build. He is clean-shaven with short hair and has one scar on his upper lip and one near his left eye.
