A thug who orchestrated a murder plot from behind bars has admitted splashing a court officer with tea.

Robert Warnock, 27, soaked Allan Doyle at the High Court in Glasgow on September 21, 2022.

An enraged Warnock threw a cup against a wall with its contents landing on the prison custody officer.

Warnock was in the cell area at the court facing a charge of conspiracy to murder.

He was behind three firebombings in Greenock, Inverclyde in 2020.

His 18-year-old sibling Reece Warnock had been brutally attacked in August 2019 in nearby Port Glasgow.

Andrew Sutherland and his half-brother Leonard Cole jnr were identified as the culprits.

Properties and relatives linked to the pair were then targeted.

Warnock was able to help organise the attacks having taken advantage of prisoners being allowed mobile phone access during the pandemic.

He was in HMP Shotts at the time serving an 11-year jail term for attempting to murder a woman and assaulting her partner.

The six men that were involved in the firebombings were given a total sentence of 64 years.

A judge told Warnock - who pleaded guilty - that he acted "like a gangster" as he sought to turn the streets of Greenock into a "warzone".

He was then locked up for 15 years and three months.

Warnock pleaded guilty today at Glasgow Sheriff Court to his latest charge of behaving in a threatening or abusive manner.

A not-guilty was accepted by the Crown to a separate charge of assaulting Mr Doyle by throwing liquid at him.

Warnock will not spend further time behind bars as Sheriff Barry Divers ordered his one-year sentence to commence from February this year.

The court earlier heard that Warnock was "shouting and causing a commotion" in the cell area.

Attempts were made by staff to calm him down.

Warnock turned to Mr Doyle and said: "F*** off before I spit on you.

"You are a glorified f***ing security guard, come here I will smash you."

Warnock then went on to pick up a polystyrene cup containing hot tea that he had been handed earlier.

Prosecutor Jennifer Sillars said: "He threw the cup towards the cell wall with some of the liquid smashing off the wall and landing on Mr Doyle.

"A colleague was able to move out of the way to avoid the contents."

The police were then notified.
