GLASGOW subway has been suspended due to a commuter falling on the tracks at a station in the city's West End. 

The underground service is at a halt and emergency services are in attendance at Kelvinbridge after someone fell on the tracks.

It happened before 4 pm and British Transport Police provided no further details surrounding the fall or the victim. 

The force said emergency services are at the scene. 

Glasgow Subway tweeted: "Both circles currently suspended due to a passenger related incident. Emergency services are in attendance. Apologies for the inconvenience. Updates to follow."

An eyewitness took to Twitter and said: "Was at a station - Kelvinbridge I think when the girls opposite me freaked out and the train coming other way came to a sudden stop.

"The girls think they heard someone shout help and there were people kneeling on the platform looking down at the tracks through the train."

Glasgow Subway later confirmed that outer circle service has resumed.
