A boy was last seen walking his dog by the beach. His Mother rang the police when he did not return home for dinner. The picture below is of the beach where the boy disappeared taken by the forensic team.

A man standing near the scene was questioned and his statement recorded by police.
"Sure I saw everything. The boy came walking along the beach with his dog behind him. The stupid thing wouldn't listen and it kept running away into the bushes. A swimmer with flippers came out from sea and set on the beach when the boy walked past him and chatted for a while. I then saw a lady follow the boy and a man came out of the bushes and followed them both. I think it was that bloke who came out of the bushes."
