Drawing pins are being left on Swansea promenade!
Swansea Council says there have been a number of reports over the last week at locations stretching from Mumbles and West Cross to the Civic Centre area.
Some cyclists have already reported punctured tyres because of the drawing pins.
The council has organised extra sweeps of the prom in the wake of the reports, but is calling for anyone with information on who may be responsible to contact South Wales Police.
A council spokesperson said: “The number of drawing pins to have been left at several locations on the prom over the last week or so makes it look like this is being done this deliberately. This is an extremely irresponsible and dangerous thing to do because it puts users of the prom at risk.
“We’d encourage anyone who sees anything suspicious or thinks they may know who’s responsible to either contact the police or the council. The prom is a terrific facility that’s enjoyed by hundreds of thousands of residents and visitors every year, so it’s hugely disappointing that a tiny minority of people is intent on spoiling the experience for the vast majority.
“We’ve urged our staff to be vigilant and have organised extra sweeps on the prom, but we’re also asking the public to be on the lookout for suspicious behaviour. The Easter holidays start this weekend, so it’s important this problem is nipped in the bud as soon as possible.”
South Wales Police are available on 101. You can also contact Swansea Council’s Parks Watch Hotline on 0800 0787357.
