Having been unable to extract any motorcycles, the criminals turned to vandalism and poured large quantities of oil all around the premises.
R&M is situated in a residential area on a main road that's very busy during the day. (It runs from Birkenhead Park to the docks and Wallasey.) There's a police building (albeit a custody suite) about half-a-mile away that's staffed 24/7. Birkenhead's main police station is less than two miles away.
At least R&M are insured. I wish them all the best because they deserve it.
