A pair of thugs launched a sickening, unprovoked attack on a homeless man before bumping fists in celebration as they walked away from their bleeding victim.
Yobs Jordan Rankmore, 29, and Joshua Alston, 22, delivered a series of brutal kicks last March to helpless Paul O’Brien, who died three days later from a brain haemorrhage.
The attack was caught on CCTV, Wales Online reported, showing the two callous men beating O’Brian as he sat in the doorway of Brewhouse in Cardiff.
Rankmore was kicked O'Brien's twice in the head while Alston also dealt a blow.
Their violence left the victim bleeding and with swelling and bruising to his face.
Mr O'Brien was later found dead at the Wallich hostel but Rankmore and Alston could not be proven to have caused the victim's death.
Speaking in Cardiff Crown Court, prosecutor Abigail Jackson said that at 6.50pm Alston could be seen throwing a crisp at Mr O'Brien before both defendants approached him.
At 6.56pm Rankmore was seen kicking Mr O'Brien to the head followed by a kick from Alston and a further kick by Rankmore.
Both men proceeded to walk off and gave each other a "fist bump" as Mr O'Brien sat bleeding in the doorway.
The victim returned to the hostel just after 7pm and was seen by staff with blood to the front and back of his hands and his face. He said he had been kicked in the face and appeared intoxicated.
On March 23, he later told a member of hostel staff he had fallen over in town and was seen with a black eye and swelling to his face.
Mr O'Brien was found dead on March 25 by hostel staff and an investigation was launched. Rankmore and Alston were identified as the individuals involved in the March 22 assault.
Both defendants were arrested on April 3. They were shown CCTV of the incident and Rankmore confirmed that he and Alston were depicted in the footage.
Following a post-mortem Mr O'Brien was found to have suffered injuries including swelling and bruising to his cheek, dried abrasions, bruising to the left side of his nose, and bruising in the lining of the lower lip.
The cause of death was given as subdural haemorrhage to the brain and blunt force head trauma.
Ms Jackson said: "This could have been caused by the assault on March 22 but the pathologist could not exclude the possibility it was unrelated to the assault."
Both men admitted assault occasioning actual bodily harm.
Heath Edwards, representing Rankmore, said his client was "sorry" for what he did, whilst Matthew Roberts, representing Alston, said the defendant has since moved away from Cardiff and has ceased contact with those he associated with while he was living on the street.
Sentencing, Judge DJ Hale said: "This was a completely unnecessary assault on Paul O'Brien which you did, as far as you were concerned, for laughs.
"He was someone you knew. You knew he was an alcoholic – he was slumped in a doorway and you couldn't resist having a kick.
"He wasn't doing you any harm – you did it for your perverted sense of humour.
"I hope it's brought it home to you how close you were to a much more serious situation – it seems Mr O'Brien fell a few days later before his death."
Rankmore was sentenced to six months imprisonment suspended for two years and Alston was sentenced to four months imprisonment suspended for 18 months.
Both were ordered to carry out a 20-day rehabilitation activity requirement and 20 sessions of a programme activity.
