As investigations into the 2013 murder of Arab-Malaysian Bank (AmBank) Group founder Hussain Ahmad Najadi have been completed, the police have closed the case.
Apart from not seeking any more suspects, the police last Tuesday have also released a witness to the killing of the septuagenarian.
Kuala Lumpur police chief Tajuddin Md Isa said: "As far as I am concerned, the investigations have been completed. No more investigation will be carried out unless new matters crop up.
"(Currently) a man has been convicted (of the murder) and is serving a jail sentence," he told a press conference after releasing official vehicles involved in the Asean Cyclefest 2015 in Kuala Lumpur today.
A Bernama report yesterday said that a local businessman who was detained at the KL International Airport on Oct 15, was released after police found no evidence to charge the 55-year-old man.
On Sept 5, last year, car repossessor Koong Swee Kwan, 45, was sentenced to death by the High Court when he was found guilty of Hussain's murder.
He was also sentenced to 18 years' jail for the attempted murder of Hussain's wife, Cheong Mei Kuen, 50.
On July 29, 2013, Hussain, 76, was shot dead and his wife seriously injured by a gunman at the carpark of the Kuan Yin Temple in Lorong Ceylon, Kuala Lumpur.
