Three more people have been arrested in connection with the murders of two 17-year-old boys at a house party.

Dom Ansah and Ben Gillham-Rice were fatally stabbed by masked attackers at the private party on the Emerson Valley estate in Milton Keynes on 19 October.

A 15-year-old boy from Milton Keynes was arrested on Thursday morning on suspicion of two counts of murder, Thames Valley police said. A 53-year-old man and a 40-year-old woman, both from Milton Keynes, were arrested on suspicion of assisting an offender. All three remain in police custody.

The 15-year-old faces two additional counts of attempted murder.

Ryan Brown, 23, and a 17-year-old boy who cannot be named for legal reasons were also stabbed in the attack and left with serious but non-life threatening injuries.

Three other people have been charged in relation to the incident. Earl Bevans, 22, of no fixed address, Charlie Chandler, 21, of Bletchley, and a 16-year-old boy who cannot be named due to his age are accused of two counts of murder and two counts of attempted murder.

The three charged suspects have been remanded in custody and will appear at Luton crown court in January.

A 27-year-old man who was arrested on 26 October on suspicion of conspiracy to murder has since been released under investigation.
