A man arrested in connection with the murder of two teenagers who were stabbed at a house party has been released under investigation.

The 27-year-old man was arrested on Saturday after Dom Ansah and Ben Gillham-Rice, both 17, were killed in the attack in Milton Keynes last weekend.

Ansah died from a stab wound to the back. Gillham-Rice was stabbed in the chest just before midnight on 19 October, police said.

On Sunday, Thames Valley police said the 27-year-old man had since been released under investigation.

Two other men have been charged over the house party deaths. Earl Bevans, 22, appeared at High Wycombe magistrates court on Saturday. Bevans spoke only to confirm his name, date of birth, that he has no fixed address and that he was represented by Wasif Ahmed.

He is charged with two counts of murder over the attack at a party in the Emerson Valley estate.

Bevans also faces two counts of attempted murder after Ryan Brown, 23, and a 17-year-old boy who cannot be named for legal reasons were left with serious but non-life threatening injuries.

He replied “yes” when he was asked if he understood the charges, but was not required to enter any pleas.

The bench of magistrates, chaired by Pat Milliner, remanded him in custody before a bail hearing at Luton crown court on Monday. He will appear alongside Charlie Chandler, 21, who was remanded in custody by magistrates on Friday.

Chandler, of Bletchley, is also charged with two counts of murder and two of attempted murder.

In an appeal on Friday, Thames Valley police threatened to identify further potential suspects still at large if they did not hand themselves in.

DCS Ian Hunter, the force’s head of crime, said: “We are still looking for others and they know who they are. I want to appeal directly to those people. We are looking for you and we will find you, however long it takes.

“At this stage we have not released your names or photographs, so please hand yourself in to the nearest police station as soon as possible. This is not going to go away and if we have to, we will name you so there will be no place for you to hide.”
