Kuala Lumpur City Hall (DBKL) advisory board member Rizalman Mokhtar said high property prices in the city as a result of corruption was a "possibility".

"The possibility of (corruption as) a contributing factor is definitely there but it is still too early for us to justify the investigations by the Malaysian Anti-Corruption Commission (MACC).

"If the rakyat wants to know, we also want to know...," Rizalman told reporters when met after flagging off the Information Department's Jalur Gemilang Merdeka convoy at the Bandar Tun Razak fire station in Kuala Lumpur this morning.

Rizalman, who is also DBKL housing committee chairperson, was asked if the recent DBKL graft case exposed by the MACC contributed to the high prices of properties in city and the disproportionate number of high-end developments.

The MACC on Aug 16 arrested a senior DBKL official with the "datuk seri" title who is believed to own 31 luxury condominium units worth RM15.5 million which he purported received for collaborating with housing developers.

The MACC reportedly described the alleged corruption as being at an "unprecedented scale" and will be questioning at least 30 more DBKL officers on the matter.

Rizalman said he was thankful that this came to light as action can be taken.

"Alhamdulillah these things (corruption) have been exposed and we hope that investigations would be carried out in a fair manner.

"Whoever is involved, if found guilty, actions should be taken (against them)," he stressed.

At the same time, Rizalman also welcomed Kuala Lumpur mayor Mohd Amin Nordin Abdul Aziz's decision that all DBKL top officers would be required to update their asset declaration documents.

"That is a good move...From there we can see if there were any possible increase in assets which does not commensurate with their incomes.

"If we can detect that (unjustifiable increase), maybe we could find 'other elements' that we are not aware of," he said.

Rizalman also expressed confidence that DBKL's top management would be reviewing its internal procedures to identify and plug any loopholes with intentions of ensuring that such a case would not reoccur in future.
