^^ its pretty well covered in camera's, ask the University security to check the cameras, if your a student depending which college you're in go ask your Bursar to pursue it (some are better than others when it comes to this). or
^ ask "heythropbikepolosoc" to ask Neil to sell you a new one with decent discount if its in stock
I've already been to chat to the security services, the particular bit i was locked up at isn't covered (apparently they can't put cameras up on some of the buildings around there as they're listed...)
I'll double check that my department doesn't having any covering that area.
Reported it to the police, not that i expect it back, just to make sure their stats reflect the state of bike theft in oxford.
