Video clips of a teenager brandishing weapons before he was accused of murder were found on his mobile phone, a court heard today.

The footage from the 17-year-old's iPhone showing large knives and Samurai swords was played to the jury.

In one clip a boy is masked as he swings a knife to the accompaniment of rap music.

A woman close to the camera is heard saying: "F--- with me, f--- with him."

In another, knives and swords are shown laid out on a bed.

The teenager is on trial with Victor Maibvisira, 19, and three other teenagers who are accused of murdering 17-year-old Kyle Yule in Gillingham.

The jury of seven men and five women also saw CCTV footage of the same teenager in a knife fight with another youth in a McDonald's restaurant.

It happened five months before Kyle suffered a fatal wound under his right armpit as rival gangs from Chatham and Gillingham clashed in East Street on Friday, October 6 last year.

In agreed admissions read out at Maidstone Crown Court, prosecutor Steven Perian QC said the teenager, then aged 16, was involved in a fight while armed with a knife at the fast food restaurant in Penge, south east London, on April 10 last year.

Mr Perian said the teenager slashed the victim, who was also armed with a knife, over the head with the weapon.

As the pair were leaving McDonald’s an elderly woman was pushed to the ground. It continued outside as alarmed shoppers scattered.

The teenager was on May 16 last year convicted of assault causing actual bodily harm, affray, battery and possession of a blade, and was sentenced to a youth rehabilitation order, a curfew and an exclusion requirement.

When aged 13, in December 2014, he was convicted of possessing a blade in south east London and sentenced to a referral order for four months.

The court has been told how Kyle was sitting in a car when about six youths arrived and started smashing the windows and slashed a tyre.

He tried to run to the nearby front door of his friend Lewis Dilallo’s home but was attacked in the small garden.

A teenage witness later identified Maibvisira, known as Vee, and two other teenagers as being involved.

She admitted she did not actually see Maibvisira knife Kyle, but stated: “I saw Vee doing a stabbing motion. Kyle was on the floor. He was against the window. He was standing up at that stage.”

Mr Perian said when one of the other teenagers was arrested he had a knife in his possession.

Another of the accused when asked if he had anything to say after his arrest, replied: “I don’t think so. If you offer me one hundred per cent protection, can I be interviewed again?”

An officer told him he could not be interviewed again and he would have to speak to his legal adviser.

Maibvisira, of St John’s Road, Gillingham, three 17-year-olds and a 16-year-old, from Gillingham, Croydon, Sittingbourne and Stevenage, Hertfordshire, all deny murder, an alternative of manslaughter and violent disorder.

Maibvisira and one of the 17-year-olds have admitted threatening "another" with a machete in Gillingham Road, Gillingham, six days earlier on October 1.

Another 17-year-old has denied affray, using unlawful violence, on that date.

The prosecution closed its case and the defence is due to start tomorrow.
