A pair of reckless youths have been filmed clinging onto a moving train at a Melbourne station.
Video obtained by 9NEWS shows the boys at the back of the train at Yarraville Station.
The City Loop train then departs the platform as the duo duck beneath the back window of the carriage.
Hanan Souki, who filmed the video, said she contacted the emergency department at the station after witnessing the “dangerous behaviour”.
Metro Trains Melbourne spokesman Marcus Williams said the video of the youths was "very concerning."
"We ask our passengers if they witness this type of irresponsible behaviour to call Triple Zero or press the emergency button in train carriages and on platforms," Mr Williams advised.
He said Metro Trains would be "working closely" with Victoria Police to investigate the incident.
