Two teenage boys who were stabbed to death by masked attackers at a house party in Milton Keynes have been formally identified by police.

Dom Ansah and Ben Gillham-Rice were fatally injured at the private event in Archford Croft, Emerson Valley, Milton Keynes on Saturday.

One of the boys died at the scene in his friend’s arms, a witness told the Daily Telegraph, while the other died in hospital.

Detective Chief Superintendent Ian Hunter, Head of Crime for the force, said the boys’ families are “uppermost in our thoughts”.

A 21-year-old man has been arrested on suspicion of murder and officers have until Thursday evening to charge or release him.

Mr Hunter said: “We are still seeking others in connection with this dreadful incident, and would again appeal to anybody who has any information that can assist our investigation to make contact with police.

“I fully appreciate the concern that this incident has caused in the local community, and would reassure anybody who has information that this will be treated sensitively and we will not tolerate any form of witness intimidation.

“We have officers and staff who can offer you the necessary support.

“If there is anybody that has information, but has not yet contacted us, I ask you to look into your conscience and come forward.

“Two families are grieving the loss of a loved one, and we are resolute in our determination to bring all of the offenders to justice.

“I again would like to say, to those who are responsible: we know who we are looking for and we will find you, however long it takes.

“Do the right thing and hand yourselves in to your nearest police station.

“To anybody who is providing assistance, or being asked to, I remind you that this is a criminal offence and could lead to your prosecution.”

Police have said that the killers gatecrashed the party, armed with knives and wearing face coverings in what appeared to be a targeted attack.

A 17-year-old boy and a 23-year-old man who also suffered knife wounds were taken to hospital with serious but non-life threatening injuries.
