Police investigating the Horizon Post Office scandal have now identified seven suspects and more than 45 “persons of interest.”

Seema Misra, from West Byfleet, was one sub-postmistress jailed for four months in 2010 while she was pregnant.

Commander Stephen Clayman is heading up Operation Olympos and says it’s a painstaking process.
