A number of vehicles have been seized by Derry City and Strabane Police.
Ballyarnett NPT had been patrolling the Skeoge area of Derry on Friday night, when they discovered e-scooters and scramblers being driven illegally.
The PSNI say that while these vehicles are legal to purchase, they cannot be driven on public roads, green areas or pavements.
They added that scramblers and e-scooters are subject to the same legal requirements as other vehicles, such as MOT, licensing, tax and insurance.
