I fall into the College SNT who have already been round to set up an appointment with their CPO but thanks for the suggestion. They've also provided a UV pen and warning stickers etc. Have been quite impressed with response.

The physical security upgrade is already in hand. New and extra lock on the communal door tomorrow and new personal door with an additional 7 lever mortice lock to make it 2 mortices plus a Yale is already ordered. Oh yes and a reinforced London bar since the current one is all bent out of shape.

Thanks for the PM, Rob. I'll check it out.
