CCTV images have been released following several illegal and anti-social large-scale gatherings of off-road bikes.

The pictures showing different men police wish to speak to regarding a number of incidents, involve cases across Merseyside.

Detective inspector Ian Warlow, said: "We have received a number of complaints of large scale gatherings of scrambler bikes and off-road bikes on public highways.

“On many occasion the bikes have been ridden not only in an antisocial manner but also the actions of those involved have been reckless and criminal.

"We know nuisance behaviour such as this is a real concern for the majority of the law-abiding public, and in particular people who have to drive on the roads on a regular basis on Merseyside, but we cannot do this alone.

"We have had considerable success in seizing bikes and each one of these taken off the road makes Merseyside a safer place but we need the public’s help in identifying the people who are riding the bikes and where the bikes are being stored.

"I want to assure the public that any information supplied to us will be acted upon."

Anyone with information to help identify these males is urged to call 101 or Crimestoppers anonymously on 0800 555111.
