Blatant Cambridge 'bike thieves' ignored by passersby

8 October 2013 Last updated at 15:35 BST

Police have criticised people for not reporting "blatant" cycle thefts in Cambridge, the UK's "cycling capital" where more than 2,000 bikes were stolen last year.

Plain-clothed officers ripped chains from bikes and sliced through locks with people nearby, but no one reported the "crimes".

The mock thefts were captured on CCTV in busy locations in the city centre.
