Former Post Office investigator insists cleared Horizon IT victim was guilty

Raymond Grant says his time was limited' after being forced to appear at inquiry over minimum witness statement

A former Post Office investigator has maintained that a branch owner-operator who had his conviction for embezzlement overturned last year was guilty.

Raymond Grant, an investigator involved in the prosecution of the post office operator William Quarm who died in 2012 not knowing he would eventually be cleared years later, had to be legally forced to appear to give testimony at the public inquiry into the Horizon IT scandal.
