POLICE are hunting a South Sydney Rabbitohs’ fan after a commuter was left unconscious when his head was slammed against a railing in a brutal railway attack today.

A number of school students witnessed the apparently unprovoked assault which detectives described as “vicious”.

Officers are currently reviewing CCTV footage following the attack on a stairwell at Ingleburn train station at 8.30am this morning.

Inspector Brad Ainsworth, from Macquarie Fields LAC, said they were looking for a man believed to be in his 20s or 30s wearing a hooded jacket with a South Sydney Rabbitoh’s logo on the back who may be able to assist with inquiries.

A spokeswoman from NSW Ambulances said the victim was unconscious with facial injuries and heavy bleeding when paramedics arrived.

He was rushed to Liverpool Hospital in a serious condition.

A high school student called Alekhya was on her way to school and witnessed a man being bashed at Ingleburn train station on the stairwell about 8.30am this morning.

“I was at the top of the stairs and the victim was walking up to catch a train and the other guy was coming down from the stairs,” Alekhya said.

“He just grabbed him and he was saying stuff like ‘shut up’ and ‘stay down’, he had his head locked up in the his legs, and every time he tried to get up he grabbed his head and slammed it against the railing,” she said.

“He was bleeding from his head and mouth and vomiting blood.

“One of my friends called the ambulance and another boy was holding the victim down to keep him safe, people from the station were giving him first aid.”

In the middle of the attack Alekhya was blocking other commuters from coming up to stairs to keep them away from the incident.

“I was trying to stop the people from coming up the ramp, I was just telling people to stay away from the incident while it was happening,” she said.

“I was very nervous but I was trying to stay strong to make sure no one else got injured.

“I’ve never witnessed anything like this before.”

Alekhya’s mother said she was glad her daughter was not injured during the incident when she called after the police arrived.

“I am proud of her,” Alekhya’s mother, who did not want to be named, said.

“She has been involved in a lot of social activity and helped people in the past who have been injured at the station,” she said.

“I am a bit worried there were a few incidents a few weeks ago at train stations, it just scares me.”

Police said they were searching for an offender who was last seen running down Oxford St who may have a female with him.
