A thug assaulted three police officers during his arrest when he racially abused a Polish officer and spat in another's face.
Lewis Wilkins, 27, was arrested in Newport city centre on March 3 last year following reports of an assault and he attempted to run away from the officers.
He was handcuffed and taken to police custody but became extremely aggressive while resisting the officers' attempts to place him in a cell.
A sentencing hearing at Cardiff Crown Court on Tuesday heard PC Gedminas Palubinskas had his thigh grabbed and twisted by Wilkins who said "We don't like each other, f****** Polish" and "Polish c***".
PC Bobby Hendry was also assaulted when Wilkins kicked him in the leg and PC Theo Mills was spat at in the face after Wilkins had cleared his nose.
It took several officers to restrain the defendant, who was kept handcuffed in a large holding cell overnight.
In a victim personal statement PC Palubinskas said: "These comments have caused me distress. My only comfort was that he spent the night in the cell and was unable to harm anyone else. I believe he's a risk to the public."
Describing the attack, PC Mills said: "I was holding his leg when he exhaled through his nose and caused mucus to fly in my face. I expect to be assaulted but to spray body fluids over my face is disgusting, unacceptable, and immorral."
A statement read out to the court from Gwent Police chief constable Pam Kelly said: "It's never acceptable to assume assaults on police officers and staff need be tolerated. It's not simply part of the the job. Assaults upon them are serious and unacceptable."
Wilkins, of Francis Drive, Newport, pleaded not guilty to three counts of assaulting emergency workers but was found guilty at trial. He pleaded guilty to racially-aggravated assault and was sentenced to a fine at Cardiff Magistrates' Court.
The court heard the defendant had 31 previous convictions which included ABH, battery, and assaults against an emergency worker.
Defence barrister David Pinnell asked whether the court would consider handing down a suspended sentence due to his client suffering from emphysema, which had left him shielding for the majority of the coronavirus pandemic.
Recorder Sean Bradley told Wilkins only an immediate custodial sentence could be justified and the defendant was sentenced to 12 months imprisonment.
