Police of China's Hong Kong have arrested a man from Southeast Asia for pushing a cleaner onto a rail track in the town of Yuen Long, according to local media on Sunday.
A closed-circuit video posted online showed that a female cleaner standing on the edge of the platform was pushed onto a rail track by a man coming up behind her.
The attacker then fled the scene, and no train was passing by at that moment.
The 59-year-old cleaner got hurt and was sent to hospital.
A police spokesperson said that officers arrested the 56-year-old suspect on Saturday near the rail stop on suspicion of assault occasioning actual bodily harm.
The police are still investigating the case.
