Our thoughts are very much with the man's family at this acutely difficult time for them.
The station was cordoned off until the early hours of Sunday morning while forensic officers conducted a thorough search and my team of detectives are working to establish the full circumstances surrounding the death, which we are currently treating as suspicious.
Three men were arrested in connection with the incident and they remain in custody being questioned by detectives.
We'll be making local inquiries, including checking whether the incident was captured by CCTV cameras, but we know that there were a number of other people at the station at the time and want to hear from them.
