Police are asking people to be vigilant of people driving mini motorbikes in an anti-social manner in Abbeymead and Abbeydale.
Recently there have been reports that the bikes are being ridden on pavements, which could be dangerous for pedestrians, and across fields.
The Neighbourhood Policing Team said it is trying to identify those who are involved.
If you see someone driving dangerously call police on 999 if they are still present. You can also report non-emergency anti-social behaviour to us online: https://www.gloucestershire.police.uk/ro/report/asb/asb-v3/report-antisocial-behaviour/
