Aylesbury shooting: Two further arrests

Two further arrests have been made over a "targeted" shooting of a man at his home in Buckinghamshire.

A 33-year-old man was found with bullet wounds to his arms and head in Stour Close, Aylesbury, on 28 March.

A woman, 32, and a 33-year-old man have been arrested in Grays, Essex, on suspicion of conspiracy to commit murder.

Two men arrested in London in June on suspicion of conspiracy to murder and attempted murder remain on police bail.

The shot man is in a serious but stable condition, police said.

Delivery driver search

Thames Valley Police said the arrest in Grays involved a search of a home.

Det Ch Insp Gill Wootton added: "I would like to stress that this remains an ongoing inquiry and the two arrests this morning are a continuation of this investigation.

"As I have previously said, we do not believe this was a random attack and believe the victim was specifically targeted at his home.

"Although he was a resident in Aylesbury, he spent a lot of his time in the north west London area, where he grew up.

"I am still appealing to members of both communities to come forward if they have any information which could assist our investigation.

"A number of people have already come forward and have spoken with officers, but we believe there are still people out there with information they have not yet shared with us.

"Now is the time to do so."

Police are still keen to speak to a man described as being dressed as a delivery driver, who was seen in the Stour Close area on the morning of 28 March.

He was white, in his 40s, about 5ft 9in (1.75m), and was wearing a green uniform and carrying a clipboard.
