Shipwreck investigated as potential cause of Sussex coast toxic plume

Maritime and Coastguard Agency considering theories, including whether chemical haze came from a wreck

Almost a week after the plume caused 150 people to seek medical treatment prompting the closure of Birling Gap beach, the source of the gas is still baffling experts.
