A drunken thug who threatened to “Raoul Moat” police officers by shooting them in the head during a booze-fuelled rampage has been caged.


David Robb downed whole bottles of Buckfast and vodka before threatening to kill the officers in his home town of Paisley.


The 29-year-old, who is originally from Renfrew but was living in Dundonald Road, in Gallowhill, lost the plot with police last week – less than seven days after being released from prison for battering his mum in her Renfrew home.


Robb threatened to gun down the officers, referencing Moat, who attacked a former partner, killed her boyfriend and shot and blinded policeman David Rathband in 2010.


Moat killed himself using a sawn-off shotgun after the shooting spree in England.


Robb appeared in the dock at Paisley Sheriff Court to plead guilty over the events of July 5 and admitted behaving in a threatening manner toward officers near Renfrew Road, Paisley.


He also admitted a second charge of assaulting PC Matthew Youden by headbutting him, while a charge of obstructing police by struggling violently with them was dropped.


The court heard that Robb was spotted lying on the ground near a footpath at around 9.30pm and officers approached.


Procurator fiscal depute Meghan Glancey said: “The accused began shouting and swearing, telling police officers to ‘f*** off’ and calling them ‘p*****’. He was eventually restrained by police officers and taken to the ground.


“At this point, the accused started to bang his head off the ground and rubbed his right temple on the pavement and shouted ‘I’ll get youse done’.


“The accused started to spit at the police vehicle and continued to shout and swear.”


Ms Glancey said one officer tried to apply a spit hood but the thug headbutted him, saying: “I’ll f****** Raoul Moat youse. I’ll f****** shoot you in the head.”


Defence solicitor Amy Spencer said Robb had only been released from prison on June 29, after being freed early from his last sentence.


As he jailed him for eight months for the latest offences and ordered him to serve the remaining 100 days of his earlier sentence, Sheriff Colin Pettigrew told Robb: “The behaviour in charge one is reprehensible to anyone. There is only one disposal – and that is custody.”


She added: “His life is something of a merry-go-round. He gets drunk, he offends and goes to custody, and that cycle is repeated again and again and again and it has done for a number of years.


“He is serving a life sentence but he is doing it in instalments of six to 12 months.”


As he jailed him for eight months for the latest offences and ordered him to serve the remaining 100 days of the sentence he was released early from, Sheriff Colin Pettigrew told Robb: “The behaviour in charge one is reprehensible to anyone. There is only one disposal today – and that is custody.”
