Police say they've tracked down more than half the bikes stolen in a single incident in Douglas earlier this week.
Some time between Saturday and Wednesday, thieves struck at the National Sports Centre, taking seven bicycles used by groups on the track there.
After an appeal yesterday, officers say they've now recovered four of the bikes - but are still hunting the last three as well as the people responsible.
