Aylesbury Shooting: Two More Bailed
A man and woman have been let out on bail after a man was shot in Aylesbury back in March.
The 33-year-old man and 32-year-old woman were arrested in Grays, Essex, yesterday morning on suspicion of conspiracy to commit murder.
A 33-year-old man was found with gunshot wounds to his arms and head on Stour Close in Aylesbury at about 10am on Wednesday 28 March.
He is still in a serious but stable condition.
In June police also arrested two men in London on suspicion of conspiracy to murder and attempted murder. They're due to answer bail at the end of the month.
Senior Investigating Officer Detective Chief Inspector Gill Wootton said:
"As I have previously said, we do not believe this was a random attack and believe the victim was specifically targeted.
"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 also want to speak to a man described as being dressed as a delivery driver, who was seen in the Stour Close area between 9.30am and 10am on Wednesday 28 March. He was white, in his forties and about 5ft 9ins. He was wearing a dull green uniform and carrying a clipboard.
Men are less likely to talk than women with 54% of women having had a conversation compared to 37% of men.
