Three teenagers charged with the murder of Jamil Palmer, from Hampton, appeared at the Old Bailey this morning.

The boys, two aged 15, and one aged 16, who cannot be named for legal reasons, spoke only to confirm their names.

They are charged with the murder of the former Hampton Junior School, Teddington School, Richmond College and Kingston College student, who was stabbed in Crane Park, near Evans Grove in Feltham, on May 6.

All three defendants have been remanded in custody and refused bail by the judge, with no formal applications made by their legal representatives at this stage.

They will next appear before the court for a plea and case management hearing on Friday, August 1.

A fourth person, a 16-year-old boy, was charged on Saturday, May 17, with the murder of Mr Palmer.

He was due to appear at Uxbridge Magistrates' Court this morning and at the Old Bailey later this week.
