--> hot chillies for the sauce. The scent of frying chillies
--> rose out of the ventilation shaft in Wasboonma's small
--> family-run restaurant before overcast conditions caused a
--> toxic-looking chilli cloud to descend on a nearby street
--> market. Shoppers spluttered and, fearing some kind of
--> chemical attack or leak, police sealed off three roads and
--> evacuated homes and businesses.

--> Three hours later, firefighters in breathing apparatus
--> eventually traced the source of the cloud, smashing down the
--> door of the (evacuated) restaurant to liberate the offending
--> batch of nam prik pao.
