Police search for men pictured walking up and down live train tracks
BTP officers attended Brighton station and searched trains arriving from Worthing but no one was found.
They have released CCTV images of three men they would like to speak to in connection with the incident.
Mr Cooke added: "These men put themselves in incredible danger by walking on the tracks.
"Passing trains are not the only hazard they faced, as this route uses electrified rails to power trains, which can kill instantly.
"At Worthing station there is a perfectly usable passenger subway that serves all platforms, so there really is no excuse for this type of behaviour.
"It was late at night and the station would have been fairly quiet, but I believe there may be witnesses who have not yet come forward to police.
"If you saw anything, or think you recognise the men pictured, please get in touch."
Anyone with information should call British Transport Police on 0800 405040, text 61016, quoting reference SSUB/B2 of 12/06/2014, or by calling Crimestoppers on 0800 555111.
