This is the best summary I could come up with:

The week-long trial heard how Mr Clarke was surrounded by a group of three teenagers after he allegedly challenged them over messing around on an escalator in the Derbion centre in Eagle Market, Derby.

Officers were called to reports of an assault at the bus station and Moumeche, from James Close, Derby, and two 13-year-old boys were arrested.

Detective Inspector Mark Shaw, who led Derbyshire Constabulary's investigation, said: "The tragic events of that day have had a devastating effect on both the families of Mr Clarke and of the defendant himself.

The senior officer added: "I hope that this case will demonstrate how important it is to stop and take a moment before resolving any matters and avoid resorting to the level of violence and the consequences seen here.

"I would like to express my thanks to the family of Mr Clarke for the dignity shown throughout the entire criminal process and hope they can look to move forward and now focus on their fond memories of Dennis."

Andrew Baxter, from the Crown Prosecution Service, said: "Dennis Clarke's tragic death was the result of this young person's intimidating and aggressive behaviour, refusing to back down and not knowing when to walk away.
