This is the moment a gambling addict suddenly shoves a young woman onto the train tracks at a Hong Kong railway station because he was having a bad day betting on the horses.

The incident was filmed by a CCTV camera at Tai Hing (North) station in the district of Tuen Mun in the Chinese autonomous region of Hong Kong on Sunday afternoon.

The husband of the victim, name not reported, filed a complaint with the police and explained that she was pushed from behind on the platform while waiting for a train.

Police spokesperson Lee Ying-chi said there were no trains passing at the time and the victim was able to return to the platform despite suffering injuries to her arms and neck.

She was sent to the Tuen Mun Hospital for medical treatment, and train services at Tai Hing (North) were unaffected by the incident.

According to reports, the police identified the suspect as a transport worker named Yau who did not know the victim prior to the platform incident.

The suspect was filmed by CCTV cameras at Ping Shan Station at about 7pm travelling in the direction of the Tuen Mun Ferry Pier. He was then arrested by officers on the scene.

The police are looking into the 33-year-old man’s mental health and also the fact that he may be a gambling addict.

According to local reports, he lost a lot of cash betting on horse racing earlier that day and took his frustration out on the passing woman.

His neighbours said he lives on his own in a flat on the Tai Hing Estate and they also confirmed that he appears to be addicted to gambling.

The investigation is ongoing.
