POLICE have stepped up patrols at Castle Cove Beach following complaints of beach parties breaking lockdown rules.
It comes after residents claimed revellers gathered on the beach, 'blaring' music, urinating in public, being sick, throwing stones and glasses - and even having sex in public.
A community group now fears the beauty spot could be closed to the public if anti-social behaviour continues.
Steve Elsworth, Chairman of Trustees of the Friends of Castle Cove Beach, said: "We have had reports that there were about 15 kids on the beach having a party on the slope. It got out of hand - people were throwing up, peeing over the edge - a couple were having sex.
