There was a report yesterday (7th March 2016) from Combe of an unsuccessful attempt to steal some paragliding equipment. The two men made a hasty departure once spotted, but it's a fair assumption they will be back.
Please ensure you keep one eye out for your own equipment and others. If you do see something suspicious, either speak to the person or let others on the hill know what you have seen.
Pilots will not mind being challenged, but remember, stay safe and do not put yourself in danger. The police are your first port of call if you are unable to resolve the situation by talking to the person.
