Tuen Mun Principal Magistrate Kwok Wai- kin said the behavior of the self-described loner, Law Hin-fat, was "disgusting" and "indecent," and that the kiss was premeditated.

Law, 24, a trainee library assistant who pleaded guilty to indecent assault, had been remanded in custody for two weeks since early November.

A spokesman for Koon said she respected the court ruling, adding it was a "proper sentence."

The spokesman said: "It sends a message to the public to respect the rights of celebrities."

A women's group said the same respect should be extended to all women.

Hong Kong Association for the Survivors of Women Abuse chairperson Liu Ngan-fung said if the defendant had done the act intentionally, two months' jail was a proper sentence. But she stressed every woman, not only celebrities, should be respected.

In passing sentence, the magistrate described Law's act as "serious, offensive and disgusting."

Kwok also dismissed Law's claim the kiss was an impulsive act, saying he did it to satisfy a desire. "If you want to show your love, you can tell her `I like you, can you marry me?"' Kwok said.

Instead, the magistrate said, Law chose to kiss her for almost 10 seconds. He was also wearing a cap and sunglasses to avoid being identified, showing the act was premeditated, Kwok said.

A psychiatric report said Law had spent almost half a year to plan how to express his love for Koon. The report also said Law was not suffering from depression and personality disorders - contradictory to a psychiatric report early this month.

In his own letter to the magistrate, Law said he had no friends, was lonely, and had problems expressing himself. Law said he deeply regretted his irrational act and had momentarily lost self- control.

In mitigation, Law's counsel, Luk King-wang, said the defendant felt "deeply remorseful."

He said Law had promised not to commit such an act again and had sent two letters of apology to Koon. He suggested a sentence of 240 hours' community service should be enough.

However, the magistrate said Law was not regretful, and that his act was outrageous, hurting "the victim, her friends and family." A custodial sentence was therefore needed to act as an effective deterrent. Kwok said he also doubted it was a momentary loss of self-control, noting Law continued to hold on to Koon after the kiss and had to be forcefully removed by others.

Law had pleaded not guilty when the case was first mentioned in court last month, but changed his plea on November 3.

On October 6, Law invited himself onto the stage of a televised show at the Gold Coast Shopping Centre to celebrate the Mid-Autumn Festival.

On stage, Law started to talk about his "lover." Koon and her fellow host quizzed him about his "lover" but he answered evasively. The three conversed and interacted with the audience for a few minutes before Law said his "lover" was in the audience, and pointed to the far corner.

As Koon strained her eyes to try and identify who Law was pointing at, Law took a step back to stay out of her line of sight, before coming forward again to grab and kiss her.

Video clips of the incident have been posted on the popular Web site YouTube. One clip has had more than 530,000 viewings.

Koon reported the incident to Castle Peak police the same night. "If I didn't report this case, he may strike again. And apart from myself, I think other artists will be scared, and even all Hong Kong girls," Koon said at the time.
