Drivers who "cruise" around with loud music booming out of their windows could have their cars confiscated, police in Birmingham warn.
Officers have been targeting drivers who have been blasting music from their cars in the Broad Street area, part of the city's entertainment complex.
A police spokesman said if they commit the offence again, the drivers will have their cars taken from them.
The operation ran over the weekend after complaints from residents.
'Harassment and alarm'
Acting Sgt Jake Flanagan, who oversaw the operation, said: "Where a vehicle is being driven in a careless or inconsiderate manner and is likely to cause harassment and alarm, distress or annoyance to anybody else, we, the police, have the power to seize that vehicle.
"Now, we will of course give a warning and anybody who commits the offence again within 12 months, we will simply take the vehicle from them."
The operation, known as Operation United, was set up after complaints about the behaviour of revellers on Broad Street from neighbour groups.
Sgt Flanagan said complaints about drinking and violent behaviour had fallen and at the last meeting, the only complaint was about "cruising".
"Not only will we tackle people cruising, but also a whole manner of other offences.
"We will be looking at all vehicles on Broad Street, from private cars to taxis and limousines," he said.
