News of the World 'undermined axe murder inquiry '

A retired detective has accused News of the World journalists of attempting "to undermine" the police investigation into an axe murder.

Daniel Morgan, a private investigator, was killed in 1987. He was allegedly about to expose police corruption.

Det Ch Supt David Cook believes links between the newspaper and ex-detectives he was investigating led to him being turned on by the tabloid.

News UK, the owner of the now defunct Sunday red top, is yet to comment.

Caroline Evans reports.
