Arresting policeman forgetful in witness box

A policeman who arrested one of the men accused of murdering Michaela McAreavey has been warned by the judge after failing to answer a question on how the suspect was dealt with.

It came shortly before the revelation that swabs taken from the hotel room where the honeymooner was strangled and sent to the UK for analysis did not contain genetic material belonging to hotel employees Avinash Treebhoowoon and Sandip Moneea.

The crime scene samples were handed to Cellmark Forensic Services lab in England for testing.
