A council is protesting to the Metropolitan Police after one its traffic wardens was arrested after he ticketed an officer's car.
The situation reportedly turned ugly after the off-duty policeman saw the warden putting an £80 ticket on his car, which was parked with two wheels on the pavement in Upminster, Essex.
According to neighbours, words were exchanged before the policeman dashed into his house, put on his uniform and called for back-up.
Then, when two colleagues arrived in a patrol car, he went back outside and arrested the warden on suspicion of using threatening and abusive behaviour. Now, Havering council has asked the Met to investigate the arrest.
According to one neighbour, the warden had just ticketed the car when the policeman, then wearing civilian clothes, began speaking to him and the exchanges soon became "nasty".
'It's hilarious to think a traffic warden can be arrested for issuing tickets – it just goes to show that even the police are fed up with them," added the neighbour.
"We're always having problems down here with wardens targeting motorists unfairly and this time one got his comeuppance."
A council spokesman said: "The council is very concerned about the arrest of its officer.
