Former Lord Mayor of Leicester, Cllr Robert Wann, disturbed two suspected wood thieves in his pub car park whilst carrying the shotgun in a display case. He reported the matter to the police who charged him with possession of an unlicensed shotgun. The gun had been disabled by removing the firing pins but non-permanent decommissioning still requires a licence.
Cllr Wann was fined £2,600 and ordered to pay £85 costs and a £120 victim surcharge although it's not clear who the victim is in this case.
