An Inverness prisoner lost his temper and was abusive towards a guard when the officer refused to identify himself, a court was told.
Nicholas Wynne from Edinburgh was serving a sentence at Porterfield Prison on July 31 when the incident took place.
Inverness Sheriff Court heard that Wynne was talking to the prison warder but did not recognise his voice.
His lawyer, Elaine Crawford told Sheriff Margaret Neilson: “He couldn’t see who he was speaking to on the intercom and asked. The officer replied that he wouldn’t be interrogated and my client lost his temper. He has been diagnosed with a personality disorder and is on anti-psychotic medication.
“He had spent a time at his own request in solitary but has now been moved to another prison”
Fiscal depute Ross Carvel said 28 year old Wynne, who admitted behaving in a threatening manner, made comments like: “If you open my cell door I will stab you.”
Wynne was jailed for six months but it will run concurrently with his present sentence which expires in September next year.
