A 16-year-old boy who denies carrying out a string of acid attacks on six moped riders in just 90 minutes appeared in court today.

The court heard the Croydon teenager, who cannot be named because of his age, will stand trial in January after he allegedly targeted the men to steal their bikes on the night of July 13, spraying them in the face with a noxious liquid.

Police said the attacks left one victim with "life-changing injuries."

The teenager is said to have stolen two mopeds and tried to take another four from their owners in a spree lasting around 90 minutes.

The defendant appeared at Wood Green Crown Court on Friday by video-link from Feltham young offenders institution.

Wearing grey tracksuit bottoms and a grey T-shirt, he spoke only to confirm his name before entering not guilty pleas to 12 charges over the July 13 attacks.

The offences include throwing a corrosive liquid with intent to "disable, burn, maim, disfigure or cause GBH", robbery and attempted robbery.

The 16-year-old also denied a further charge of robbery of a moped on June 25.

The offences are said to have taken place in the evening in north and east London.

Judge Noel Lucas QC remanded the youth in custody until the trial on January 8 at Wood Green Crown Court, which is expected to take up to seven days.
