A prisoner has gone on the run from Castle Huntly jail near Dundee.
Police Scotland said 33-year-old David Moran was reported missing at 12.50pm on Friday.
It is believed that he has connections in the Falkirk and Livingston areas.
He is described as being 5 feet 10 inches tall, of slim build, clean shaven and with short brown hair.
When he was last seen he was wearing a black jumper with white writing, blue t-shirt and black tracksuit bottoms.
In 2015, Moran was jailed for five and a half years at the High Court in Glasgow after assaulting a member of staff in a bookies in Livingston.
When the female employee held on to the money at the Ladbrokes premises he produced a canister and sprayed her in the face before running off.
“If seen, members of the public should not approach him and should contact Police Scotland on 101 or 999,” said a Police Scotland spokesman.
