A cyclist was knocked off his bike by what appeared to be a nylon rope strong across the Prospect Park loop early Wednesday evening.

The extent of the cyclist's injuries is unclear—an FDNY spokesman had no record of first responders being called to the park for such an incident yesterday. But one witness says he passed by the scene around 4 p.m. and tells us the rope, which appeared to be "regular nylon rope" or some sort of climbing rope, was strung diagonally across the road.

The rope was "lower in the jogger and cycling lanes and higher in the car lane," the witness recalled in an email to Gothamist. "Looked like a car could fit under it in that lane. That's where I was riding so it went over my head when I rode past."

The cyclist who was clotheslined was biking in the cycling lane. According to the witness, "he had folks by his side very quick and first the parks department pulled up and then a detectives car came a little later." An NYPD spokesman could find no record of the incident.

We've reached out to friends of the cyclist and will update if he agrees to tell us more about the incident. But it's worth noting because this isn't the first time this has happened; in May 2014 a cyclist sustained six broken ribs and a fractured elbow after biking into a clothesline strung across the road in Prospect Park.
