A violent robber pretended to be a Good Samaritan before subjecting a drunken victim to horrific violence in an alleyway.
Daniel Bradley, 30, inflicted serious facial injuries with “gratuitous” blows to his victim’s head before throwing him to the ground.
Bradley - who was high on cocaine - then “scavenged” through the man’s pockets as he lay prone on the ground.
Leeds Crown Court was shown CCTV footage of Bradley approaching the victim on Lower Briggate, in Leeds City Centre, at 1.50am on January 7 this year.
Footage showed Bradley putting his arm around the victim and appearing to help him before calmly leading him down an alleyway.
Bashir Ahmed, prosecuting, said the victim was clearly drunk, disoriented and struggling to walk.
Bradley propped him up against a wall in Blayds Yards and subjected him to the assault.
The victim was punched six times before being pushed forcefully to the ground.
He suffered a serious fracture down the length of his cheekbone and dislocated his left shoulder.
Bradley took £40 from his pockets before walking out of the alleyway back on to Lower Briggate.
The victim was rescued by volunteers from Leeds Street Angels who heard his cries for help.
Bradley, who earns £400 a week working as a welder, was arrested after being recognised when police launched a Facebook appeal.
A probation officer recognised his picture from dealing with him after he was convicted of a previous violent offence.
Bradley, of Winrose Approach, Belle Isle, Leeds, pleaded guilty to robbery.
The court heard he has previous convictions for violence.
In 2005 a victim lost an eye after being attacked by Bradley in a nightclub.
Narinder Rathour, mitigating, said Bradley would like to apologise to the victim and was sorry for what he had done.
Mr Rathour said: “In his own words, it was the biggest mistake of his life.
“He says he is likeable when he’s not under the influence of anything.”
Bradley was given an extended prison sentence totalling nine years, four months, after judge Robin Mairs said he considered him to pose a serious risk to members of the public.
He said: “This was a barrage of blows against a vulnerable and utterly defenceless man. This was without question very significant force.
“When on the ground you scavenged through his pockets and took what you could.
“What is striking about what I have seen is your controlled manner when you first entered the alleyway with him and then left.”
“This was not some drunken escapade. It is very clear from the pictures I have seen that you knew exactly what you were doing.
“There was an element of planning to this as you took him out of public view so you could inflict this violence upon him.
“You were well aware of what you were doing and you were well aware of the damage that you were causing.
“The affect of your offending will live with him for a very long time.”
After the case, Detective Inspector Al Burns, of Leeds District Crime Team, said: “Bradley cynically preyed on the victim after deliberately targeting him as someone he could easily take advantage of due to him being drunk.
“He pretended to be a Good Samaritan who wanted to help the victim but led him down an alley out of public view and subjected him to a sickening assault before going through his pockets and robbing him.
“The level of violence he used was completely unnecessary given the victim’s intoxicated state and left him with serious injuries that needed hospital treatment.
“We hope the victim can take some comfort from the significant sentence of imprisonment that Bradley has received.
“He was brought to justice as a direct result of information from a number of members of the public who contacted us following a media appeal, and we would like to thank those people for assisting the investigation.”
