Teens attack man on train after he asked them to turn down their music (video)

A shocking video has gone viral, showing a violent altercation on a Sydney train over the weekend. 

Onlookers were left terrified as a group of teenagers turned on a man who asked them to turn down their music. 

The incident, on the T1 Western Line between Redfern and Strathfield occurred around 11.55pm on Saturday, June 20, and has sparked a police investigation. 

Footage shared by a Sydney news aggregator Instagram account shows the chaotic scene on the top level of the carriage as multiple teenagers punch the man while onlookers watch in distress. 

It then escalates as the man is pulled down the stairs by the group, who continue to deliver blows on the back of his head. 

According to a witness on board the train at the time, the trouble began when the group allegedly boarded the service at Central Station, according to the Instagram account. 

The witness claimed the teenagers were drinking vodka and blasting loud music, disrupting fellow commuters. 

When the male passenger reportedly asked them politely to turn the volume down, the situation turned violent.
The teenagers allegedly responded by pushing the man before launching a physical attack on him. 
 

According to the social media post, the service was delayed at Strathfield Station for approximately 15 minutes following the incident. 

Police were allegedly called to meet the train at the platform, but the majority of the group managed to flee the scene before officers arrived. 

The witness claimed that after running off the train at Strathfield, the group allegedly appeared to be heading further west towards Penrith. 

Following their escape, the train driver made an announcement over the PA system to check if the victim was okay.

The driver asked whether the man required medical attention and advised him to step off the train, as an ambulance was already on its way. 

However, the man reportedly declined to get off, choosing to continue his commute despite the ordeal. 

Police are now calling on the public to help track down the teenagers.
