Noxious fumes filled part of Soho, London causing widespread concern, the alert of the specialist terrorism unit and hospitals being placed on standby. The culprit was Nam Prik Pao, a Thai restaurant preparing its famed red-hot chillie dip. Fireman - in full breathing apparatus - discovered a 9lb pan of red chillies being burnt on the stove in preparation for making the dip. Whilst everyone the surrounding area had streaming eyes and were choking from the fumes, the chef was preparing his delicacy completely unprotected. 'We are used to the smell,' he said.
