Video shows the moment five killers stormed teenager's birthday party brandishing knives and weapons in Milton Keynes

Warning: Some my find scenes in video released by police distressing

The film, taken from CCTV footage in Emerson Valley, shows the five offenders brandishing knives, one of them a couple of feet long.

It also shows four of the defendants sullenly refusing to talk to police after they were arrested, and answering 'no comment' into all their questions about how 17-year-olds Dom Ansah and Ben Gillham-Rice died.

And it shows heartbreaking interviews with the parents of Dom and Ben, describing how the pair had been inseparable friends since they were in reception class together.

Today defendants Earl Bevans, 23, Clayton Barker, 20, Ben Potter, 17, Charlie Chandler, 23 and his 17-year-old brother Jamie Chandler were all jailed for life for murder. They were given a total of 126 years. See the Citizen story here.

Bevans was the only one who admitted what he did. All the other denied double murder and prompted a trial lasting seven and a half weeks.
