SIX people are being quizzed by police after ‘unknown substances’ were found during a drugs raid at a property in Knutsford.

Around 110 residents were evacuated from their homes on Longridge after a drug warrant was executed at around 7am on Monday, November 27.

A large number of police officers and fire and ambulance vehicles surrounded the property and a 100-metre cordon was put in place as a precautionary measure.

Bomb disposal experts spent all day working to identify the nature of the substances.
