A FOURTH man is wanted in connection with an assault at a farm where a former gangster was murdered last month.

Paramedics tried to save William ‘Billyboy’ Martindale, 39, at Meadow View Farm off Mill Lane, Ongar, on the night of Friday September 7, but he was pronounced dead at the scene.

A post mortem later revealed he had died from serious head injuries.

A 54-year-old friend of Mr Martindale’s, was also found at the farm with serious head and chest injuries and is now recovering at his home in Barking.

Factory worker Paul Groves, 33, was charged with the murder of his neighbour and causing grievous bodily harm with intent to Mr Martindale’s friend.

Mr Groves of Queensway, Ongar is remanded in custody and will enter a plea at Chelmsford Crown Court on December 3.

But detectives are now keen to identify a fourth man who was at the poultry farm on the night of the murder.

Senior Investigating Officer, Detective Inspector Marina Ericson, said: "We are looking to locate a fourth man who was present at Meadow View Farm on that Friday night and is wanted in connection with the assault on the east London man.

“This man is described as white, is in his mid-late 30s, has a bald or closely-shaven head, is of medium to stocky build and is approximately 5ft 11ins tall.

“We would urge anyone who knows this man or where he lives to contact us.”

A 66-year-old man of the same address as Mr Groves remains on bail until October 26 after he was arrested on suspicion of assisting an offender.

Mr Martindale of Cripsey Avenue, Ongar, was a self-confessed former gangster and had been questioned over two murders in the past.

As well as detailing his criminal past on his website, billymartindale.co.uk, he was in the process of writing his autobiography ‘Billyboy’, to tell the true life of a gangster.

Anyone with information should contact detectives at Brentwood’s Major Investigation Team on 101, email them on SCDappeals@essex.pnn.police.uk or call Crimestoppers anonymously on 0800 555 111.
