Anthony Smith absconds from Castle Huntly prison
Police are searching for an absconder who has failed to return to an open prison after being allowed out for home leave.
Anthony Smith, 32, was last seen in Croxteth, Liverpool, on Wednesday afternoon.
He had been due to return to Castle Huntly prison near Dundee, but did not do so.
Smith is serving a five-year sentence for drug offences and a two year and six month sentence for assault.
He was jailed in March 2012 along with his brother after admitting being concerned in the supply of drugs.
At the time police said the pair had been "intent on flooding" Aberdeen and Shetland with heroin.
Smith is 5ft 10in tall, with a stocky build and short brown hair. He also has the name Bobbie tattooed on his left arm.
He is originally from Liverpool but also has relations in Aberdeen.
Police Scotland has appealed for anyone with information to contact them.
A force spokesman said: "He is known to travel on public transport and has friends and family in the Aberdeen and Liverpool areas."
