The damage was discovered by a climber who alerted the BMC. Graham Lynch, BMC Access Officer, then visited the crag and the BMC have followed this up with a strongly worded letter to the school.
This is not the only chipping to take place at Shipley Glen recently. It was reported on Rocktalk on 25 September that another person was discovered hacking away at the rock. On this occasion it was assumed that the person was just trying to carve their name in the rock but possibly that wasn't the case. With the events happening so close to each other could there be a connection?
