Not a load of rubbishCity law firms should put concealed cameras around their rubbish bins, the solicitor who acted for Jonathan Aitken and Neil Hamilton warned last week, following a documentary about bin-scavenger Benjy Pell.A Channel four documentary last week revealed that Mr Pell had taken rubbish bags from Michael Coleman's firm - London-based Harkavys - in 1999, when he was acting for Jonathan Aitken and James Hewitt.Mr Coleman destroyed all the firm's sensitive used documents and put false information in his rubbish, so that it would be clear if someone was stealing it.This strategy proved successful when a foreign journalist made contact with the firm to check on the accuracy of one of the false stories in the bins.Subsequently Mr Coleman placed concealed cameras near the bins, and an image from one of these led to Mr Pell's prosecution.Mr Coleman last week cautioned City law firms to be similarly cautious.He said: 'During Pell's trial it was revealed he had stolen bins from Peters & Peters, Freshfields and Simons Muirhead & Burton on the same night he robbed our bins.'Mr Coleman said that all City firms should shred sensitive documents and keep video cameras tracked on their bags.

'We kept ours hidden in flower pots,' he said.Jeremy Fleming
