A scissors attacker who was caught with enough drugs to make more a million tablets of street diazepam was today jailed for five years.

Paul Harvey, 33, struck a victim in the neck with the makeshift weapon at a house party in Glasgow.

But during a subsequent search at his address in the Blackhill area of the city police found a tub containing more than a kilo of the Class C drug Etizolam - also known as fake valium, blue plague or 'blues'.

Harvey, formerly of Drumpellier Street, in Glasgow, was originally charged with attempting to murder Patrick Curley, 23, following the attack at a flat in Zena Place on March 3 last year.

But his guilty plea to a reduced charge of serious assault by striking him on the neck with a pair of scissors was accepted. He also admitted being concerned in the supply of etizolam on June 3 last year.

Lord Woolman told Harvey at the High Court in Edinburgh that the injuries sustained by Mr Curley in the attack were "life-threatening".

The judge said: "To stab someone in the neck is highly dangerous. It could have been fatal."

The stab wound entered the victim's larynx just above the vocal chords. He underwent surgery and was left scarred.

The judge pointed out that Harvey was under the influence of cocaine and drink when he carried out the assault after he got into an argument with his victim.

He told him: "These crimes represent an escalation in your offending behaviour."

The court heard that Mr Curley was at the Ranza bar in the Blackhill area on the evening of March 2 with friends and Harvey later joined the group.

One of those present decided to host a party and the others joined him at the flat after the bar closed.

But about 7 am the next day Harvey and Mr Curley got into an argument in the kitchen. The younger man left the room but returned and Harvey picked up scissors and struck him once in the neck before leaving.

Scissors with the victim's blood on the blades were recovered by police from a bin bag containing rubbish.

During the later search at Harvey's address police found the haul of street diazepam powder.

The court heard that it could be bought from illicit online dealers for between £300 and £600, but had the potential to produce more than 1.1 million tablets.

Harvey maintained that he was just storing the recovered drugs after he ran up a drug debt.

Defence counsel Stephen Hughes said Harvey accepted that he "overreacted" in the scissors attack.

He said: "It is also fair to say that the amount of controlled drugs which he had consumed played a part in that decision."
