Passengers were evacuated from a train at Leeds railway station this afternoon (Friday) over concerns about a suspicious substance.
Travellers were ordered off the East Coast service from London at about 2pm after the on-board leak.
Police and firefighters were called to investigate and a cordon was set up near the scene at platform six.
A British Transport Police spokesman said: “BTP officers were called to Leeds rail station to a report that a potentially harmful substance had leaked on board a train.
“The incident was reported to BTP at 1.58pm and officers met the train, the 12.05pm London Kings Cross to Leeds service, as it arrived into Leeds station.
“Passengers were asked to vacate the train while specialist officers and West Yorkshire Fire Service worked to establish the nature of the substance.
“The item is believed to have been brought onto the train in a passenger’s luggage and leaked onto other bags.”
Initial enquiries suggest the liquid is not harmful.
“There have been no reported injuries to anyone on board the train, and officers are now working to determine the full circumstances of the incident,” the spokesman added.
No services were significantly delayed as a result of the problem.
