NORTH Wales Police are investigating reports of off-road motorbikes speeding through woodland in Abergele and Rhyd y Foel.
Police are now asking witnesses to report sightings of the bikers immediately so they can deal with the issue.
Earlier this week, the Local Democracy Reporting Service reported how the motorcyclists were riding around ancient forest behind Gwyrch Castle in the Tan y Gopa Woods and Coed Plas Uchaf woodland.
Residents, landowners, and councillors complained the bikers were destroying the habitat by wrecking the forest floor and running over bluebells and wild garlic.
Others complained of trespassing, noise, fumes, and fires being lit and said the bikers were also riding on public roads in Old Colwyn without wearing helmets.
Now North Wales Police are appealing for witnesses.
A spokesman commented: “We are aware of reports involving individuals riding motorbikes in woodland close to Gwyrch Castle and areas nearby.
“These incidents are currently under investigation, and we are working closely with partner agencies, including Natural Resources Wales who manage the woodland.
“We would urge the public to continue to report these types of incidents as soon as possible so that the issue can be dealt with proactively by officers.”
Abergele councillor Andrew Wood branded the bikers “hooligans” earlier this week.
A spokesman for Natural Resources Wales revealed the incidents have continued this week.
“We were contacted on March 27 after motorbikes had been seen accessing land we manage at Gwrych Castle,” he said.
“We have spoken to the Gwrych Castle Preservation Trust and North Wales Police about this matter and will work with neighbouring landowners, including the Trust, on how we can prevent this kind of activity taking place.
“We encourage people not to approach or engage with people illegally using motorbikes on our land and to report the matter to police and the NRW incident line on 0300 065 3000 when it is safe to do so.”
A spokesman for the Gwyrch Castle Preservation Trust spokesman said: “The safety and amenity of visitors and local residents is paramount. Unfortunately off-road dirt bikes have been a long-standing issue and an injunction was served some years ago.
“We will work with our tenants NRW, along with North Wales Police, and Llanddulas and Rhyd-y-Foel Community Council, on how we can prevent this kind of activity taking place.”
