GWENT Police is looking for Stephen Peter Lima who failed to return to HMP Prescoed on Thursday (AUG 21) having been on day release.
Lima, 24, was convicted of supplying class A drugs at Cardiff Crown Court in March 2011 and sentenced to nine years in prison.
He is of mixed race, 5ft10" tall, of medium build and with black hair and brown eyes.
It is believed there may be a potential risk to the public due to the fact that he is no longer in the custody of the prison service.
If anyone sees him or knows of his whereabouts they are advised not to approach him but to call police on 01633 838111 quoting log 401 21/08/14.
