According to this report the police had doctored Colin Caffell's statement.
"Along with Jeremy’s statement, the detectives also questioned Colin Caffell. It’s not surprising that Sheila’s ex-husband should not wish to believe Sheila was capable of murdering her own offspring, and his doubts merely fanned the flames of Stan’s prejudice. Whatever was said between Stan and Colin, Essex police tried to hide the original hand-written statement of Colin Caffell and later replaced it with an altered, typed version. The police also failed to disclose the fact that Colin had complained in respect to this discrepancy, and that Essex police had failed to correct it. In brief, the police turned Colin’s statement from ‘I’d had a rough deal (from the Bamber family) all along…’ and put the words in Jeremy’s mouth instead. Colin complained to Stan Jones about the mistake, who told him: ‘It’s only a typing error… don’t worry about it.’ Colin did worry about it and wrote a letter of complaint to DS Ainsley: ‘When I asked Stan Jones about it again last week he said: ‘leave it, whatever you do don’t say anything about it in the witness box; it’ll cause all sorts of trouble if you do…’ In 2002, Colin agreed that the error may have merely been a ‘clerical mistake.’) Nothing Colin Caffell had to say eased Stan’s suspicions that Jeremy might be involved."
