During the last fortnight there has been a spate of thefts from vans in the Oxford City area.  On each occasion a spare wheel has been removed from either the rear or the underside of the vehicle. This type of theft requires the use of tools, so the offenders(s)would probably be with the vehicle for a few minutes or so.
If you see anyone acting suspiciously around parked vehicles, please call the police on 999 or if you have any historical information relating to these offences please call the Neighbourhood Watch Office on Oxford 335133.
