Sentence has been delayed on a teenager who admitted stabbing a diner in a fast food restaurant after a man appeared in court with him this week on similar charges.

Aiden St Louis, of Lewis Crescent, Cliftonville, was due to be sentenced yesterday after admitting wounding with intent to cause grievous bodily harm and having an offensive weapon.

But he will now have to wait until after the trial next February of Mohammed Gedi, 21, who denied wounding with intent and an alternative charge of unlawful wounding.

St Louis, 18, knifed the victim in McDonald’s in New Road. Gravesend, in the early hours of July 16.

The attack was filmed on a mobile phone and also caught on the 24-hour restaurant’s CCTV cameras.

The film showed St Louis stamping on his victim before lashing out with the knife as other diners were begged him to stop.

The victim needed surgery in a London hospital to repair a muscle.

The court heard he had not supported the prosecution.

“There is a history of much lower level violence and this attack appears to have been at a level which leads me to think his risk must be assessed,” said Judge Charles Macdonald QC when St Louis entered his plea on September 1.

He was remanded in custody for reports to assess dangerousness.

Prosecutor Tom Dunn said although the two were charged under joint enterprise law, it was St. Louis who wielded the weapon.

Gedi, of Winchester Road, Higham Park, Chingford, Essex, and St. Louis appeared together by TV link with Elmley Prison.

Gedi was not represented because his solicitor and barrister failed to attend court.

Judge Martin Joy continued with proceedings after Gedi indicated how he wished to plead to the charges.

His trial was set for the week beginning February 19. Both he and St Louis were remanded in custody.

A third man wanted in connection with the stabbing has not been identified.
