DARRELL Desuze went on a school trip to see police riot training in action a year before he launched his fatal attack.

He was part of a group of year 10 boys from Isleworth and Syon School who visited the police riot training centre in Gravesend in the summer of 2010.

According to the school newsletter, the outing was organised specifically for students considering a career in the police force.

A report in the newsletter concludes: “Darrell Desuze, for one, found out that a career in the Metropolitan Police certainly would be a lot more interesting than he had originally imagined.”

The newsletter described how pupils were able to ‘see first hand the challenges that face officers in extreme crowd order scenarios’.

Youngsters saw a simulated riot with bricks thrown at officers and different crowd control techniques.

The Chronicle has an exclusive picture of Desuze aged 14, above left, when he appeared at an End of Year Jam musical event held at the Paul Robeson Theatre in Hounslow on August 28, 2009.

Euan Ferguson, headteacher at Isleworth and Syon School, said: “It was a huge shock to learn a former student of the school has been involved in the riots and that their involvement had such tragic consequences. Our thoughts are with the friends and family of Richard Mannington Bowes.

“The sense of shock nationally that anyone could have committed such a crime is strongly shared in the school community.

“These were the isolated actions of an individual who had left school and the judge has seen fit, by naming Darrell, to make an example of his actions.”
