Police have stepped up patrols to tackle nuisance bikers at Bunny Fields in Calverley and at Ravenscliffe Woods.
Officers from the Leeds District Off Road Bike Team have been carrying out patrols in both areas following ongoing reports of nuisance and illegal off-road bike activity.
Patrols were conducted as part of targeted tasking in response to concerns raised by local residents and landowners.
A police spokesperson said: “Officers identified clear signs of recent bike activity within the woodland and track areas, and patrols in both locations will continue moving forward.
“We will continue to work with local communities and landowners to tackle anti-social riding and protect public spaces for everyone to enjoy safely.”
Bunny Field and Ravenscliffe Woods are popular with walkers but have experienced problems with off-road bikes for a number of years.
