Noxious smoke from 9 pounds of burning chilies at a Thai restaurant prompted fears of a chemical attack in London, the BBC reports:
"Police closed off three roads and evacuated homes following the alert.
Specialist crews broke down the door to the Thai Cottage restaurant at 1900 BST on Monday where they discovered the source - a 9lb pot of chillies.
The restaurant had been preparing Nam Prik Pao, a red-hot Thai dip which uses extra-hot chillies which are deliberately burnt.
But the smell prompted several members of the public to call the emergency services."
You won't find the recipe for the offending dish in the Anarchist Cookbook, so the BBC thoughtfully provides one for its on-line readers. Just don't whip up a batch without alerting the Bobbies first.
