A MAN spared jail over a threat to attack his mum after claiming he'd murdered three people has avoided prison again - for calling police out to a house just to shout 'disgusting' abuse at them.

James McAllister — who has more than 30 previous convictions — pleaded guilty to behaving in a threatening or abusive manner and shouting and swearing, whilst on a community payback order.

McAllister, 34, served a nine-month prison sentence last year after chillingly telling police that he'd stabbed three people to death at the Star Hotel in Port Glasgow.

He had earlier phoned a senior social worker and told her that he was going to 'chop people up'.

Following his release, McAllister caused a disturbance at Inverclyde Royal Hospital and declared: "I'm going to go home and slit my throat and attack my mum."

He was on an 18-month supervision order and attending enforced drug and alcohol counselling sessions for that incident in February when he committed his latest offence.

The police abuse incident at an address on the Port's Slaemuir Avenue on September 5 was described in court as a 'glitch' in McAllister's current payback order.

Defence lawyer David Tod told Greenock Sheriff Court: "He has difficulties but it is accepted that these are exacerbated by drink."

Sheriff Andrew McIntyre said: "There will need to be a substantial number of hours of unpaid work given his record for this kind of thing."

The sheriff told McAllister: "Your CPO was going well and it's a shame you committed this additional offence.

"It is quite disgusting that you treated police officers in this way.

"You called them out and then you behaved like this."

McAllister, of the Port's Bardrainney venue, has been told he must complete 135 hours of unpaid work within nine months.
