A detective who wrote a damning report on the way his colleagues investigated a child’s death has been criticised for making “extraordinary assumptions based on hearsay”.

Robert Krykant, from Abingdon, claimed he was victimised and harassed by his managers and even ordered to re-write the document by the Acting Assistant Chief Constable.

It came after the 57-year-old stated that senior officers had inadequately handled an investigation into the death of a four-month-old baby boy.

He is suing Thames Valley Police for constructive dismissal claiming he was forced to leave his job.

However, giving evidence at the employment tribunal in Reading, Det Supt Claire Stevens, said: “When I read through the report I felt it was confused and made extraordinary assumptions. These do not appear to be to based on fact and seemed to have a significant amount of hearsay.”

Another officer, Detective Chief Inspector Linda York, of the Professional Standards Department, said he had jeopardised a murder investigation.

The tribunal continues.
