Crawford & Company's international investigation services manager Will Gaskell has been poached by competitor VFM Services.
He is the second fraud expert to leave Crawfords in the past year.
Gaskell's colleague Gabrielle Ashley left Crawfords in October 2001 to set up Absolute Customer Management with former Direct Line anti-fraud head Bill Trueman.
Gaskell worked for VFM's managing director Bill Jackson when Jackson established a conversation management system at Thomas Cook's travellers' cheque division.
He will look after VFM's sales, marketing and customer relations functions.
