Police investigating the nerve agent poisonings of five people in Wiltshire have released drone footage of officers searching a shallow stream in a Salisbury park.
Officers can be seen peering into the water and combing a bank in Queen Elizabeth Gardens, one of the spots Dawn Sturgess visited with her partner, Charlie Rowley, the day before they collapsed having been exposed to novichok.
Police have found a bottle that contained novichok at Rowley’s home in Amesbury, eight miles north of Salisbury. One theory is that one or other found the bottle in the park and sprayed it on their hands.
The stretch of water being searched is a branch of the river Avon that splits off from the main waterway north of the city centre and joins back up with it just south of the park.
