Police called to a domestic dispute chased after the alledged aggressor because he swore at them, a court heard.
Lincoln magistrates were told the officers had been informed that the man involved in the domestic incident had ridden away on a blue mountain bike.
Jim Clare, prosecuting, said police saw the bike and tried to speak to the defendant.
“They wound down the police vehicle window and told him to stop but he swore at them and rode on,” Mr Clare said.
“An officer then chased him on foot. The defendant looked back and shouted more abuse.”
The man was then arrested and cautioned and responded with more abuse.
The 22 year old, from Lincoln, admitted using threatening words likely to cause distress on June 29.
He apologised for his behaviour.
“I had a stupid argument with my family. I was upset and not thinking straight,” he said.
Magistrates said his behaviour was unacceptable towards the police who “work on behalf of the citizens of this city and this country”.
They fined him £50 and ordered him to pay a surcharge of £15
