A prisoner who was jailed for carrying out two armed robberies on a petrol station in Jedburgh, Scotland, in 2009 has received a further four-month sentence.

Perth Sheriff Court was told Craig Stevens, formerly of Jedburgh and Kelso, was caught sneaking drugs and mobile phones into Castle Huntly open prison near Dundee on September 21 last year.

Stevens had been let out to perform voluntary work for a day but was caught on his way back in with two mobile phones hidden in his underwear.

He also had two mobile phone chargers, some prescription tablets and syringes of liquid which contained testosterone and horse steroid trenbolone.

Stevens was jailed for five years in 2010 after stealing £180 in two raids on the Shell Garage in Jedburgh while armed with a knife in August 2009. Witnesses said he wore a scarecrow disguise.

He also committed a knifepoint robbery of the former Somerfield supermarket in Hawick in May 2009, taking £350.

Sheriff Michael Fletcher added four months to the end of Stevens current.
