A Brentwood man was arrested in connection with a rape in Chelsmford over the weekend

The family of a private detective found with an axe in his head will meet police and prosecutors today to discuss failings in the investigation into his death.

Daniel Morgan was killed in 1987 in a south London car park, but no-one has been brought to justice for one of the longest unsolved murder cases on Scotland Yard’s books.

Three men were cleared of killing Mr Morgan in March last year, leading to apologies from lawyers and the police.

In the meeting with representatives from the Metropolitan Police and the Crown Prosecution Service (CPS), the family will ask what they describe as the “deeply corrupt” relationship between the Met and News of the World journalists. Mr Morgan is believed to have been close to exposing the close connections between the two when he was murdered.

They will also quiz lawyers and officers about supergrass evidence.

Scotland Yard have admitted that the first inquiry into the 1987 killing was hampered by police corruption and the Morgans will demand how subsequent investigations were affected.

The five police inquiries and an inquest, as well as three years of legal hearings, are unofficially estimated at £30 million.

Mr Morgan’s brother Alastair said: “All of the available evidence indicates that Daniel was murdered because he was about to expose serious police corruption and that after his murder his private detective agency, Southern Investigations, became the hub of industrial-scale police/press corruption.

“This was the beginning of a deeply corrupt relationship between the Metropolitan Police and News of the World journalists.

“We want to know how this interfered with the five subsequent investigations into the murder and the political response to allegations of police involvement in Daniel’s murder.”

The CPS confirmed the meeting will take place at their London headquarters.
