Emergency services rushed to a Letchworth car dealership earlier today as a man suffered from breathing difficulties after coming into contact with an unknown “hazardous substance.”

At around 10.50am this morning, police, ambulance and fire services were called to the SEAT car dealership in Icknield Way, to reports of a man in difficulty inside his car.

A Herts police spokesperson said: “It was reported that a suspicious, unknown substance had been found inside a vehicle at an industrial unit at around 10.50am. The ambulance and fire services were also in attendance, alongside CBRN officers and investigations are being carried out.

“At this time, there are not believed to be any suspicious circumstances.”
