Concerns have been raised that a flick-knife found on a busy residential street in Derry could have fallen into the hands of local children.
The knife was found at the bottom of Rosskeen Park in the Hazelbank area of the city.
The discovery was made last Friday and the knife was handed over to local Sinn Fein representatives.
Sinn Fein Councillor Eric McGinley said it was only through good fortune that the knife had not ended up in the hands of young children who might have flicked out the blade accidentally and cut themselves.
He said: “I want to highlight the dangers of this type of weapon and anyone fooling about with this is liable to stab themselves, or it could end up some other child being stabbed.
“I am just grateful that this has been taken off the streets.”
In the north it is illegal to carry a knife in public, with a maximum four year jail term, although Swiss Army-style knives are legal as long as the blade is shorter then three inches.
