Police are still hunting a man following an incident in which armed officers were called to Huddersfield train station.
A man went onto the tracks and fled into one of the tunnels on Tuesday night, leading to police closing the tunnel which caused widespread disruption to train services.
It happened after West Yorkshire Police officers had gone to the station as part of drug dealing investigations at about 8pm.
Armed police were drafted in and at 9.35pm officers tweeted: “For the safety of train users and the man involved the tunnel was closed resulting in ongoing disruption to train services.”
People tweeted pictures from the station and described the situation as a “stand-off.”
Trains were cancelled and there were reports the station had been evacuated while police dealt with the situation.
By 10.20pm the tunnel had been reopened.
Supt Pat Casserly from West Yorkshire Police said: “We are progressing a number of lines of investigation. It cannot be stressed how dangerous it is for any people to go onto railway tracks and for this reason we closed that tunnel to rail traffic to ensure the safety of the suspect and officers. Appropriate officers, including armed officers, were deployed to the station due to the nature of the wider investigation.”
