Video of a Victorian train conductor attacking another man has gone viral.
The man being attacked has been charged in relation to the alleged assault of a woman on the train on Saturday, Victoria Police said in a statement.
"Police are also investigating allegations of an altercation between the Croydon man and a public transport employee at Broadford Railway Station. The Croydon man has declined to make a statement at this stage."
The footage begins with the conductor kicking the man on the ground, before he stands up and a brief scuffle breaks out between the pair.
Tony Morton from the Public Transport Users Association told 3AW that the incident was obviously against protocol.
"What should have happened there was if there was a passenger assaulting people, there should have been police summoned to the station at Broadford to deal with the situation."
V/Line has told BuzzFeed News they are assisting Victoria Police with their investigation.
Transit Crime Investigation Unit detectives are investigating the second incident. Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
