A killer was targeted in a revenge attack hours after he dumped a dying man near a hospital.
Declan Davidson set about Ben McCulloch after it is believed he watched him torture pal Stephen Quigley on a horrific social media post.
The drama unfolded after killer McCulloch dumped Stephen next to a closed section of Paisley's Royal Alexandra Hospital, close to where he was later found dead. When he returned to his Barrhead home, 26-year-old Davidson pounced, leaving him with severe facial injuries, the Daily Record reports.

McCulloch pled guilty at the High Court in Glasgow last week to killing Stephen, from Neilston, during a savage attack in March 2021.
He admitted dropping the fatally injured 26-year-old at the closed area of hospital, just six minutes from A&E.
It is believed Davidson witnessed the attack on Snapchat and went to the killer's home to help his friend, where he assaulted McCulloch, leaving him badly injured on the street.
Davidson, also of Barrhead, was later jailed for two years at Paisley Sheriff Court after pleading guilty to carrying out the attack under provocation.
A source said: "Davidson went crazy when he saw the footage of Quigley being attacked.
"He went there to help him and found only McCulloch.
"He'd no idea his pal was lying dying somewhere. He got there too late to save him."
While investigating Stephen's death, police appealed to the public for help and revealed the attacks were linked.
The High Court in Glasgow earlier this month heard Stephen, who was disorientated, tried to walk to A&E for help after being dropped off but was found dead outside a daytime ward the next morning.
The court was told the pair had been drinking in McCulloch's flat, and were "in good spirits, uploading video clips to social media", and that Stephen would have survived if he had received immediate medical treatment.
McCulloch, who was initially charged with murder but admitted the lesser charge of culpable homicide, was warned he faces "a lengthy period in prison" when sentenced.
His dad, Brian McCulloch, was part of a multi-million-pound drug gang jailed after a police surveillance sting similar to TV show The Wire.
The High Court in Glasgow heard in 2009 that officers interpreted coded conversations after bugging a house and a car.
Brian McCulloch was caged for 10 years while Steven Caddis, Stephen George Jamieson and Gary Caddis were jailed for six, eight and five years respectively for supplying illegal drugs.
During the surveillance, police raided properties in Glasgow, Paisley and Clydebank, recovering drugs with a street value of £9million, along with firearms and almost £500,000 in cash.
All four admitted supplying cocaine, while McCulloch, director of SBS Developments in Paisley, also admitted dealing amphetamine and ecstasy.
The gang's multi-million-pound cocaine operation brought misery to the streets of Paisley and other towns and villages across the west of Scotland.
They were nabbed after officers from the then-Strathclyde Police force bugged Jamieson's home and his expensive BMW X5 car.
Jamieson was the original target but evidence was compiled against McCulloch, then of Paisley, after he bought the bugged BMW.
A ring of steel was thrown around the High Court in Glasgow ahead of their sentencing hearing, amid fears of an escape bid from the gang.
Officers from the tactical firearms unit, armed with sub-machine guns, stalked the court building while the police helicopter circled above.
The police operation, codenamed Operation Lockdown, ran from August 2007 to February 2009, involved up to 100 officers on any given day and cost an estimated £2.7million.
In addition to the convictions, the operation resulted in the seizure of significant sums of cash, drugs and property.
