A trust at the centre of a police fraud investigation has set up a confidential phoneline so staff can voice concerns to external auditors.

Lifecare trust chair Frank Birch resigned last month as Surrey police confirmed they were investigating 'apparent financial irregularities' at the trust's Caterham headquarters. Chief executive Ian Semple agreed to take special leave.

Acting chief executive Don Marquis has now revealed that finance director David Healey has also taken special leave while marketing and corporate planning manager Rosemarie Mitchell and works and estates manager Peter Poynter have been suspended.

The trust stressed that the police investigations do not directly involve any of the named staff.

Accountants KPMG have been asked to carry out a 'stock-take' of 'where the organisation is now and where it needs to move to in terms of systems and procedures'.

A trust newsletter urges staff to be 'as open and helpful as you can' and includes a phone number to reach auditors in confidence.

Six people have been arrested and bailed as a result of the Surrey police investigation, which centres on subcontracting.
