From the February 2010 minutes of the Trellech United Community Council:
REPORT BY PC SIMON HOLDER
Several crimes had been reported in the area. Some lambs had been stolen from Llanishen, and some timber from forestry close to Trellech. Several prolific thieves were known to be in the area, and residents were warned to keep their property secure. Old Land Rovers have been a particular target for thieves.
He regretted that the neighbourhood watch system has suffered from financial cuts.
The Neighbourhood Watch scheme in Penallt seems to have fallen into some disrepair in recent times and is now being replaced by a new system called OWL, the Online Watch Link. See here for more details.
