A severed goat's leg has been left rotting on top of a bus stop in Clapham Junction for at least a month.
The leg is sitting on top of bus shelter Y on Saint John's Road, and it is not clear how it got there.
Commuter Riz Wasti posted a picture of the leg to his Twitter page, alerting the council by writing: "@wandbc seeing this leg of lamb at bus stop Y near Clapham/Northcote road for few months. Prob welldone by now?!"
Wandsworth Council responded by tweeting Transport for London (Tfl) about the issue.
According to the Wandsworth Guardian, Suzanne Perkins, a graphic designer from Battersea, said she was horrified when her friend pointed out the leg on the bus stop roof.
She said: "I was at the bus stop with a friend and she said 'do you realise what's up there?' and I had a look. You can see very clearly a hoof and a hip bone.
"She said it's been there since March. It's not just like it's been there for one or two days – it has been up there for a month.
"Why has it been there so long? What is going on with general street cleaning?"
Tfl reportedly told the Evening Standard it was now taking action to remove the leg.
