The home and former offices of Hong Kong media tycoon Jimmy Lai, an outspoken critic of Beijing who also played a prominent role in large prodemocracy protests last month, were firebombed early Monday, a spokesman said.

The first attack took place around 1:30 a.m. local time when an unknown car reversed up to Lai's house and threw an object that exploded into flames when it hit the gates. About 20 minutes later, one or two other incendiary devices were thrown at the gates of Next Media Ltd.

"This is a continual effort to try to intimidate the press in Hong Kong," said Next Media spokesman Mark Simon. "This is raw and pure intimidation."
