A pizza chain is 'investigating' after a food waste recycling bin was spotted overflowing with raw dough.

It appears the dough had risen up and spilled out from within the dumpster on Crown Street in Edinburgh.

The remarkable sight - which resembled a 'dough monster' made out of pizza ingredients - was spotted by Twitter user Ailsa Burn-Murdoch during her morning commute.

She tweeted: 'I have a feeling @PapaJohnsUK owe a local sanitation worker free pizza for a year.'

Social media users on Twitter have nicknamed the spectacle the #doughmonster.

Papa John's replied they were 'currently investigating this further directly with the store' but offered no explanation.
