The incident happened shortly after 3.30am on Saturday, 26 April, at the entrance to the station. Investigations to date have enabled officers to isolate CCTV images of a woman they would like to identify and speak to as they believe she can assist with their enquiries.
A woman approached the station concourse's entrance doors which were closed and locked at that time of the morning. Realising she couldn't gain access to the station, the woman hit the glass pane first with her hands and then with her high-heeled shoes, causing the glass to crack
