Police and ambulance teams are currently dealing with an incident at Aylesbury Railway Station.
Part of the station concourse close to Morrisons is cordoned off, and police at the scene are telling onlookers to move on.
One eyewitness said that she saw a man fall from the Bourg Walk bridge, but this has not been confirmed.
Police say they were called at 11.39am to reports of a man having been injured on the railway by Station Way.
More to come as we get it.
