Teenager guilty of boy's murder

Martin was stabbed to death near his home in Holloway, north London, within an hour of dirty looks being exchanged between two groups of youths.

He was chased by a gang and left dying on the street in June last year.

The 16-year-old was found guilty of murder after only five hours of consideration by the jury at the Old Bailey.

A 17-year-old was found guilty of attempting to cause grievous bodily harm. He was cleared of murder and manslaughter.

Rene John-Baptiste, 21, of Plaistow, east London, and Sean Clark, 19, of Holloway, were cleared of all charges.

The two juveniles cannot be named because of their ages. They were remanded in custody for sentencing on August 8.

All the defendants had denied the charges.

Martin, a pupil at St Aloysius College in Archway, lived on a local housing estate where there was rivalry with youths living on another estate.
