London airport evacuated after 'CS gas' incident

A suspected CS tear gas spray was found at London City Airport after passengers and staff were evacuated following a "chemical incident" that left 27 travellers feeling unwell and halted flights.
London's innermost airport re-opened three hours after the incident was first reported yesterday, after 500 people were evacuated and several passengers treated for breathing difficulties.
A search of the airport "led to the discovery of what is believed to be a CS gas or spray", Scotland Yard police headquarters said in a statement.
"Whilst the cause of the incident has not yet been confirmed, officers are investigating if it was the result of an accidental discharge of this canister.

"Officers are investigating whether it may have been discarded by a passenger prior to check-in.
"There have been no arrests and enquiries continue."

The London Ambulance Service said two casualties were taken to hospital and 25 treated at the scene for breathing difficulties.
David Morris, 28, said he was at the check-in desk for his flight to Edinburgh.
I was talking and started to cough to the point I was not able to keep talking," he said, calling the situation "quite scary"
"Within two minutes, they shouted for everyone to get out," he said, with check-in staff jumping over their desks.

"Everyone was shouting and rushing towards the door."
The London Fire Brigade was called to "reports of a chemical incident" at the airport in east London's Docklands, which caters mainly for business travellers and short-haul flights.
It said the terminal was "ventilated, searched and declared safe", adding that "no elevated readings" had been registered during the search.
Several incoming flights from destinations such as Frankfurt, Amsterdam and Paris were diverted to other airports or cancelled.
The airport said there would be continued disruption to flights and urged passengers to contact their airlines.
