The assailants reportedly tied up two security guards before entering the house, with the witness sustaining injuries to his face and hand, reported The New Straits Times.

“The attackers also warned him to just stay at home and not become a hero,” said a source.

Petaling Jaya police chief Shahrulnizam Ja’afar confirmed the incident and said a team from the criminal investigation department was at the scene.

The lead prosecutor in Lim’s case, Wan Shaharuddin Wan Ladin, said the prosecution would raise the matter when the trial resumes on Aug 19.

Lim is charged with using his position as then Penang chief minister to ask a businessman for a 10% cut of the profits from the undersea tunnel project and accepting RM3.3 million in kickbacks.

He is also accused of two counts of dishonestly misappropriating RM208.7 million worth of state land.
