I think it is just a mistake because I have seen the same locks locked to the railing before so I assume they just leave them there. I would just leave it until next week but could do with the bike tomorrow. Cheers
Got to uni this morning, bike still there with both locks on. Called the peelers and explained the situation but they said they cant do anything until its been stolen. Going to have a word with hospital security now.
Chopped them off just now, thanks for the help.
