walker

Joanne, a dog walker, came across "over a dozen" large nitrous oxide canisters scattered on the grass during one of her frequent walks at the beauty spot on 12 October.

When the knifeman spotted a dog walker he "straight away attacked him ... so many times", she added.

Conrad went to the bedroom to grab his father’s walker.

"I thought some walker was just waving to me but as I got near him I realised this man's distressed so I stopped and I said 'Are you Ian Currie?',"

But as the garden has grown, its eldest and most mature plants have started shielding its youngest, and walkers have been more careful about where they step.
