Hong Kong  - A Kung Fu grandmaster, who trained under the same teacher as martial arts star Bruce Lee, has been jailed in Hong Kong for assaulting his mistress, a court report said Friday.

Leung Ting, the founder of the internationally known Wing Tsun Association which has tens of thousands of members, was sentenced to two months for the assault on Rita Lip Sik-ying, 45, his lover of five years.

The prosecution said the assault occurred in March after the couple rowed over a matter relating to Leung's former wife.

Lip told court Leung pushing her down, banged her head on the floor, kicked her in the stomach and boxed her ears, a report in the South China Morning Post said.

Leung, 62, pleaded not guilty, claiming a hysterical Lip had banged her own head against the floor because he would not give her money.

His lawyer told the court Leung's professional career may be damaged by a conviction.

Leung, who began practising Kung Fu at the age of 13, has directed 24 Kung Fu television series and six films. He has also written more than 50 books and instructed special forces and the military in many different countries. (dpa)
