Andrew Frost, aged nine, was presented with the £25 book token by Acting Inspector Mark Soderland during a school assembly.

Inspector Soderland, who is currently in charge of policing in the Forest South Inspector Neighbourhood Area, said: "The competition was run following an initiative managed by the Courts Service, during which pupils from Forest Primary Schools took part in a mock trial.

"The schools involved, which totalled 15 in all, were invited to submit entries to the poster competition and, although the standard of entries was very high, we thought that Andrew’s poster was definitely worthy of winning first prize.

"We are always very keen to engage with local schools on such initiatives and encourage young people to have a positive view of their local police force. We are consistently impressed with the response such activities gain from our local schools and their pupils."
