An Onchan resident says they've reported irresponsible cyclists to police after seeing them in a banned area.
They took to an Onchan Facebook group to issue the warning after encountering cyclists at the Clypse Reservoir walkway.
They say cyclists are lifting mountain bikes over a gate to ride on narrow footpaths, in defiance of signs forbidding bikes.
And they say they've reported the cyclists to the Department of Environment, Food and Agriculture as well as police.
