Knifeman waved two blades at Coatbridge family gathering

Airdrie Sheriff Court heard James Jarvie brandished two knives and warned: "I'll deal with you properly."

Jarvie, 43, admitted acting in a threatening or abusive manner in Drumpark Street, Coatbridge, on June 27 this year while on bail for three other matters.

He also admitted carrying a knife in public without reasonable excuse.

Jack Lindsay, prosecuting, said the couple were in the garden with relatives, including children, and friends about 9.30pm.

He told the court: "Jarvie, who was known to the couple, approached the back gate of the property.

"While walking past he stated, 'When I see you, I'll deal with you properly.' 

"He removed two large knives from his jacket and brandished them towards the witnesses, causing them fear and alarm.

"Jarvie made off but the police were contacted and officers found him in Mitchell Street, Coatbridge, around 10pm.

"He showed them a bush outside a property where he had left the knives."

Defence lawyer Roberto Manini said Jarvie, who admitted previous convictions, has had hospital treatment for mental health problems.

Mr Manini stated: "At the time of this incident, he was on anti-psychotic medication that was not working.

"He exacerbates his problems by taking illicit substances.

"Sometimes what he remembers isn't the reality. On this occasion there was a perceived slight. 

"There clearly wasn't and this must have been a terrifying incident for those in the garden.

"My client is now on the proper medication and seems to be in a better place."

Sheriff Derek Livingston noted this was Jarvie's fourth conviction for an offence involving a knife and jailed him for 28 months.

The sentence was backdated to June 29 as he has been in custody since his arrest.

The sheriff told him: "This was aggravated by involving two knives and a number of people, including children."
