Said Mr Liu, 22, in Mandarin: 'I was talking to my mum when I boarded bus number 145 from Boat Quay.'
He said the bus had about 20 people in it.
Soon after he sat down, he claimed that a man sitting some rows behind him told him aggressively to keep his voice down.
'I was still talking to my mother. So I lowered my voice. She kept asking me what was happening. I didn't want to worry her, so I told her it was all right,' he said.
After he finished the conversation with his mother, he turned to look at the man.
'He was still scolding me, gesturing with his hands and feet. He made his hand into the shape of a gun and pointed at me. Then he kicked his legs about, in a threatening manner,' said Mr Liu.
He claimed the man then rushed over and started beating him up.
'He just came at me, held my neck and rained blows down the right side of my face,' he said.
No one on the bus stepped forward to help, he claimed.

'My attacker was holding my neck, and banging my head against the bus seats,' said Mr Liu.
He shouted for help and for someone to call the police.

That was when Mr Liu's assailant tried to get away.
'He ran towards the opened door at the back of the bus. But I didn't want him to get away. So I ran after him and grabbed his arm,' said Mr Liu.
Three young men boarded the bus to help Mr Liu.
'After I told them what happened, one of them said to the man who beat me, 'The sign in the bus says no smoking, no eating, no littering, but where does it say no talking on the phone?' said Mr Liu.
Another man also boarded the bus to help Mr Liu apprehend his attacker until the police arrived.
'An ambulance arrived first and while the paramedics were tending to me, the police arrived,' said Mr Liu.
He was sent to the A&E at
ATTACKED AGAIN AT HOSPITAL
'At the hospital, I saw my assailant. He also came to the hospital because he said his arm hurt. When he saw me, he made a lunge for me again, in front of all seven or eight policemen,' said Mr Liu.
The police managed to restrain him.
After his injuries were treated, Mr Liu went to the Central Police Station to give another statement.
