London City Airport declared safe after ‘chemical incident’
LONDON — More than two dozen people were treated for breathing difficulties in a suspected chemical incident that sparked the evacuation of London City Airport Friday, fire and ambulance services said.
After a three-hour investigation by police and firefighters in protective clothing, the terminal was declared safe. Police were not treating the incident as terrorist-related, and said they were investigating whether a canister of tear gas discarded by a passenger was the cause.
Police and the fire brigade said they were called just after 4 p.m. (1500GMT) Friday to reports of passengers at the airport feeling unwell.
With a fire alarm sounding, some 500 travellers and staff were evacuated to a parking lot and the tarmac near the airport runway.
