Gloucestershire Live has reported an allegation that a man on a bike pooed in his own hands and threw it at the windscreen of a driver who beeped at him.

The claim, made anonymously on the Spotted Gloucester Facebook page, reads: “To the man who poo’d in his hands and lobbed it at my windscreen because i beeped at him down london road that is vile and disgusting i beeped and pulled over because you were riding your cycle scarily”

The person who posted the message fails to expand on why they found the person’s cycling so terrifying.

Nor they give any explanation for their willingness to stop and wait for this spirited dirty protest to play out before them. (We presume there was a moment before faeces hit windscreen when it had already become clear that something was happening that might possibly not qualify as a family-friendly spectator sport.)

The ensuing Facebook comments oddly fail to attribute such behaviour to all cyclists, and road tax, helmets and cycle lanes don’t even get a mention. Make of that what you will.

One user claimed: “This scumbag threw poo at me Aswell” – a conclusion that was seemingly based solely on the offender’s modus operandi, ruling out the possibility that an organised gang could be responsible for a whole spate of attacks.

The police are not believed to have been contacted over the incident.
