Abandoned bikes

Found this study (http://content.tfl.gov.uk/bicycle-recycling-schemes-London-scoping-study-april-2007.pdf) that states:

In London, the Metropolitan Police Service (MPS) receive approximately 210 cycles per month, with roughly 40% being ‘crime related’ and 60% having been collected, presumed abandoned, from the streets.
These cycles are initially stored at local police stations whilst attempts are made through the website immobilise.com to trace the owners. This website now fulfils the function of a central property database for the MPS. The cycles are kept for 6 weeks, and then disposed of. As our research on projects around London has shown, many of these bikes are given to local recycling projects working in the community with young offenders etc. Those that are in very poor condition, rusty or badly damaged are disposed of at scrap yards. The remainder are sent to Central Property Services in Southwark.
Central Property Services hold regular auctions to dispose of bikes. In the last year, all but 7 of the bikes were sold, the average price being approximately £20. No analysis has been made of who purchases the bikes, although the MPS is aware that some dealers attend the auctions.
