Four men arrested over the murder of missing chef Claudia Lawrence will not face any charges.
The men, who are all in their 50s and from the York area, were arrested last year.
Miss Lawrence, 35, disappeared after leaving her house on Heworth Road in York on 19 March in 2009.
North Yorkshire Police said the decision not to charge the four men had been taken by the Crown Prosecution Service.
The arrests – made in March and April of last year – came after a review of the initial investigation into Miss Lawrence’s disappearance was launched in 2013.
Det Supt Dai Malyn, who led the review, said he believed the investigation had been “compromised by the reluctance of some, and refusal of others, to co-operate with police inquiries”.
He said: “I am sure that there are some people who know, or who have very strong suspicions about, what happened to Claudia.
“For whatever reason, they have either refused to come forward, or have been economic with the truth.
“I am left with the inescapable conclusion that this case could still be solved if only people were honest with us.
“The fact that they are not is agonising for Claudia’s family and they should be ashamed of themselves.”
