'Carbon monoxide' alert at logistics firm Kuehne and Nagel
Six people at a logistics firm have been taken to hospital suffering from possible carbon monoxide poisoning.
A total of 33 people at the Kuehne and Nagel depot in Draycott-in-the-Clay, Staffordshire, were assessed by paramedics.
Two men and two women were taken to hospital in Burton-upon-Trent, and a man and a woman taken to Royal Derby Hospital. Their conditions are unknown.
The BBC has approached Kuehne and Nagel for a comment.
West Midlands Ambulance Service said the incident was initially sparked shortly before 13:00 GMT after a woman reported feeling ill and it "quickly became apparent" she was suffering from the effects of carbon monoxide poisoning.
Ambulance officials added: "A number of other patients then began coming forward. Ambulance staff worked quickly to assess them all in order to establish the severity of their conditions."
