A police car was issued with a parking ticket while officers were helping a 'vulnerable' man.
Nottinghamshire Police said the policewoman on duty was responding to reports of a man in need of assistance.
A passer-by filmed the traffic warden issuing the fine in Beeston, Nottinghamshire last Friday (17 August).
Nottinghamshire County Council said it has now cancelled the fine: "We regret that the parking notice was issued inappropriately. It has been cancelled and the police have been informed.
"We have also spoken to our contractor NSL who will be reminding staff of their responsibilities."
