Pro-democracy activist Leung Kwok-hung acted in self-defence by pushing a man who took objection to his political views, a court heard yesterday. Leung, 43, a core member of the April 5th Action Group, told Magistrate Julia Livesey that he pushed Wong Keen-wah, 54, in the face because he thought Mr Wong was going to hit him. 'I found it so disgusting that he pointed his finger at me and I felt I was being humiliated,' Leung told Kwun Tong Court. 'As I spoke to him, he suddenly rushed towards me and I felt I was under threat and therefore I pushed him away.' Leung has pleaded not guilty to assault. The court has heard the incident flared outside Kwun Tong MTR station on May 22 when Leung was collecting signatures for the June 4 commemoration of the Tiananmen Square massacre. Mr Wong allegedly approached, yelled at campaign volunteers and tried to stop two students from signing. A verdict is expected tomorrow.
