Thug knocked officer out during Leeds city-centre struggle then smeared blood across police van
He was left with memory problems and headaches
An officer was left unconscious after chasing down and tackling a suspect in Leeds city centre.
Daniel Town has been jailed for the attack that left the officer laid on the floor.
The 37-year-old was found guilty of ABH after a trial, but admitted criminal damage and a public order offence.
He was sentenced at Leeds Crown Court this week, appearing over a video link from HMP Leeds where he was being held on remand.
Officers had spotted suspicious behaviour involving several people behind the Three Legs pub on The Headrow on the evening of June 1.
When trying to intervene, Town took off running, chased by the officer.
Catching him up, they grappled and in the melee the officer was knocked unconscious, prosecutor Danielle Beaumont said.
In a victim statement, the officer said he still suffered headaches and memory problems as a result.
Town was handcuffed and put in the police van, where he repeatedly hit his head against the van wall and smeared his blood.
He made threats to “bang out” officers and spit at them, then subjected a female officer to a torrent of sexist abuse.
Town has 31 previous convictions for 60 offences, including ABH, GBH, affray, kidnapping, disorderly behaviour and assaults.
Mitigating, Matthew Stewart said Town maintained he did not punch the officer, but accepted he hurt him during the scuffle.
He said there was “no excuse” for his comments to the female officer and had apologised.
Town was living St John’s Hostel on Hyde Park Road at the time, that he was recalled until July next year and accepted that a new sentence was “inevitable”.
The judge, Recorder Gordon Stables, told Town: “It was more than just a transient injury, it has had lasting consequences.”
He jailed him for 21 months.
