Rescue Dummy, Get Robbed

A man was attacked and robbed after he jumped into a lake believing a boy was drowning, only to find it was a dummy.
The dog walker was approached by a "distressed" couple in Foxes Forest, Portsmouth, who said their son had been attacked by a swan in nearby water.
When the 48-year-old jumped into the lake and discovered the dummy he saw the man going through his coat pockets.
