A racist thug bit a taxi driver before threatening to hunt down and rape a police officer's children.
The Liverpool Echo reports that James Ryan flew into a rage after two cabbies refused him and his girlfriend fares because of their "aggressive" behaviour.
Liverpool Crown Court heard John McEneaney was waiting in his hackney cab, at a taxi rank on Hanover Street in Liverpool city centre.
He saw a man and woman trying to get into the back of a cab in front, who looked like they were being "aggressive" to the driver, who drove off.
Paul Blasbery, prosecuting, said the man - Ryan - then turned to Mr McEneaney and said: "I suppose you're not going to f***ing take us."
Mr McEneaney decided to drive away, but said Ryan's girlfriend bent down in front of his cab, he believed to try and pull off his registration plate.
Ryan used a vile slur against Mr McEneaney before kicking his cab - damaging the fuel cap - and punching his window, trying to smash it.
Mr Blasbery said Ryan, 39, then tried to pull off his left wing mirror, so the victim got out and said: "Just move away from the cab lad."
Ryan knocked him over, when the cabbie banged the back of his head, before he straddled him and bit the left side of his head.
Mr Blasbery said Ryan, from Walton, continued to "punch him and bite him whilst he was defenceless on the floor".
He said Mr McEneaney "to his credit managed to overpower him" and get to his feet, but Ryan again forced him down and punched him.
When the victim got up a second time, Ryan said "I've got knives, I'm going to f***ing stab you, you're only a f***ing pensioner" and reached into a holdall, so Mr McEneaney got back in his cab, locked the doors and drove off.
He flagged down police in Ranelagh Street, who arrested Ryan shortly after the attack, at around 11pm, on May 23, 2019.
The victim was treated at hospital for two "superficial" head wounds and given a hepatitis vaccine course, which came back all clear.
Ryan was taken to a police station, but in the early hours of May 24 racially abused a custody officer, who was checking on his welfare.
Mr Blasbery said Ryan yelled "f*** you porky pig" and twice used the N word against Steven Sharp, at around 2am.
He later punched a hatch when Mr Sharp lifted it and shouted: "F*** you n******, I'm going to rape your kids n*****, when I get out of here I will find your details, come round and rape your kids f***ing n*****."
Ryan repeated the rape threat at 3.50am and when other detainees arrived, shouted: "Spit at them, the f***ing n*****s."
Mr McEneaney said the attack aggravated a previous back injury and he was off work for two months.
The victim said he lost around £2,400 in earnings and it cost £300 to repair his taxi.
The prosecutor said: "He cannot believe someone would do this to another person."
Ryan admitted a racially aggravated public order offence when he first appeared at court, but denied assault causing actual bodily harm and criminal damage until the opening day of a trial.
He has 13 previous convictions for 21 offences, with his last conviction in 2014.
Mr Blasbery said they included "racially or religiously aggravated violence", common assault and assault causing actual bodily harm.
Michael O'Brien, defending, said he wanted to highlight Ryan's "positives" and urged the judge to spare him jail.
The lawyer said Ryan had responded well to previous supervision and after being homeless now had stable accommodation.
Judge David Potter said Ryan was "very substantially intoxicated" on drink or drugs or both, when he targeted Mr McEneaney.
He said: "You bit him to the side of his head and continued to rain down punches whilst he was defenceless on the floor."
Judge Potter said "mercifully" the injuries were not as serious as they might have been, but his victim had feared infection.
The judge told Ryan: "At the police station you continued to be aggressive, shouting and swearing, using obscene racist language at a custody officer, who was doing his job in checking on the welfare of you, a lawful detainee in a police station.
"You not only used racist language towards him, but you threatened at one stage to rape his children."
Judge Potter added: "That was outrageous behaviour."
Jailing him for 20 months, he said: "Licenced taxi drivers provide a valuable service to the community in difficult and often dangerous circumstances and they can expect to feel protected in their workplace."
Ryan turned to a woman sitting in the public gallery and said: "I love you, goodbye love, see you soon kid."
