GREEN PARTY leader Caroline Lucas called yesterday for an inquiry into a bank holiday billow which forced coastline evacuations across East Sussex on Sunday.
Some 150 people required treatment for stinging eyes, sore throats and vomiting after the chemical cloud congealed on the south coast.
Noxious substances have been known to drift across the channel from European factories, but the Met Office said that was unlikely to be the cause of this incident.
“Neither the gas nor its source have been established, but agencies are continuing to investigate and have not ruled out either on-shore or off-shore locations,” a Sussex Police spokeswoman said.
Ms Lucas said: “It’s clear we need an urgent investigation to establish how this gas came to be in our atmosphere and engulfing our beaches and an action plan put in place to ensure this never happens again.”
