Police are investigating after a cyclist suffered a concussion and head and back injuries having fallen victim to a cord tied across a cycle path between Gowerton and Killay, near Swansea.

Wales Online reports that another cyclist, Adrian Critten, saw David Stacey lying on the ground near Oakwood Drive on his way home from work at around 5.40pm on Tuesday.

“I have come across a litter bin on part of the path in the past and pulled it aside thinking it was just kids mucking about, but seeing this cord being pulled across causes a huge amount of concern.

“The ride at that point is a bit tricky and there’s a sharp dip where you have to maintain speed, you’re thinking a lot at that point about control and your speed, there’s a lot of things going on in your mind so to have that in front of you is crazy.

“It is ridiculous and very dangerous. I just hope it’s kids and not part of a campaign like last year when someone put tacks along the path. It would be better if it was a one-off.”

Stacey said: “I remember something forcing me off my bike around neck to head height. I didn’t see it coming at all. I thought there was nothing in front of me and I didn’t see anything.

“When I came to, two or three people were helping me as we waited for police and the ambulance. I was taken to Morriston Hospital and I was diagnosed with a concussion and stayed there overnight and discharged at 11am this morning.

“It must have knocked me out cold. I’m just glad I had a helmet on. There was a big dent in it, and the consultant said if I did not have it on it could have been a really serious incident.”

A spokesman said that South Wales Police was investigating.

“Enquiries are ongoing, and officers are working with local partners to investigate and identify those responsible. Cyclists in the area advised to be vigilant and to report anything suspicious.”

Stacey added: “If somebody knows anything I’d encourage them to come forward. I don’t know if people were doing this for bedevilment but they need to realise how dangerous it could have been.”

Anyone with information should contact 101, or Crimestoppers anonymously on 0800 555 111, quoting occurrence 1800202617.

Last week we reported how a cyclist hit his head on a rock after wires were strung across a cycle trail in a country park near the New Forest.

The incident occurred exactly three years after a similar one we reported on at the same location.
