Noxious fumes at Leeds train station have seen the concourse sealed off and a number of shops evacuated this morning.
Several members of staff at the station’s Starbucks coffee shop were reportedly suffering with watering eyes and nausea and are being treated by ambulance staff following the incident which was reported at around 9.55am.
It is believed the fumes were the result of an unknown substance reacting with cleaning fluid being used by staff.
A spokeswoman for British Transport Police said: “Specialist officers and West Yorkshire Fire Service are now working to establish the nature of the substance.”
The main station has remained open and the incident is not affecting train services. The police cordon at the concourse was lifted at around 12.15pm.
