A man appeared in Kowloon City Court on Monday accused of trying to help one of the Abby Choi murder suspects flee Hong Kong.

Lam Shun, 41, is charged with assisting Choi's ex-husband Alex Kwong with an alleged bid to escape to Macau by yacht on February 24.

Kwong is in custody along with his brother and father after the trio were earlier charged with murdering socialite Choi, whose dismembered body was discovered last month.

Lam, who works at a yacht company, was released on bail and is due back in court on May 8.

The murder suspects are also expected to return to court that day, along with the brothers' mother who is accused of perverting the course of justice.
