Haringey Borough Commander Victor Olisa has revealed he called for an investigation into the police treatment of Down's Syndrome teenager Abdulkarriem Al-Faisal before a complaint was lodged by a member of the public.

Speaking to the Haringey Independent, Mr Olisa said that allegations made by Mr Al-Faisal's family in the Evening Standard newspaper "horrified" him.

He immediately referred the case to the Directorate of Professional Standards, who handle complaints against the police.

Mr Al-Faisal, 19, was given a caution for burglary after being found inside Haringey Sixth Form Centre in White Hart Lane on the May bank holiday Monday.

Family members have described the treatment Adulkarriem by the police as “outrageous”, alleging that he was kicked and forced to the floor by police officers, despite having a heart condition and learning difficulties.

A Haringey police spokesman has said they will not comment further on the case while an investigation is ongoing.

They have previously told journalists that proper safeguards for vulnerable detainees were followed.
