Nearly 100 motorbikes have been seized this year as part of a crackdown on antisocial bikers in Aberdeen.
Police run Operation Trinity every summer to reduce the number of bikers riding illegally or dangerously in communities across the city.
This year, 95 bikes were taken off the streets and 63 people were charged with various offences.
Officers said there was a 38.8% reduction in incidents reported to the police compared to 2014.
Chief Inspector Nick Topping said: “Antisocial use of motorbikes is predominantly an issue at its peak in the summer months, which is why we run the operation from April to August.
“It is particularly positive to see that when compared with figures for 2014, there has been almost 40% fewer incidents reported.
“This is a direct result of the proactive way the Operation Trinity team has dealt with incidents and also from the support of local communities who have provided information.
“Although Operation Trinity has concluded, officers will still deal robustly with any reports of motorcycles being used anti-socially or illegally.”
Councillor Martin Greig, chairman of the Aberdeen Community Safety Partnership, said: “Trinity has been a targeted, effective campaign and will have enduring impact through work of community police teams.
“This tackles a genuine priority amongst the public.”
