A Malaysian Anti-Corruption Commission (MACC) team raided the office of a state executive councillor in Komtar on Friday morning.
The officers stormed the 53th floor of the state administration office at about 11.30am on Friday.
MACC officers were seen entering the office of state Welfare, Caring Society and Environment Committee chairman Phee Boon Poh.
The latest raid is believed to be a follow-up to the MACC's investigations into an illegal factory in Kampung Sungai Lembu.
The officers are currently at Phee's office and pressmen are prevented from entering the office.
On Thursday, anti-graft officers also seized documents relating to the Kampung Sungai Lembu factory from the Seberang Prai Municipal Council (MPSP).
Several MACC personnel took documents from a councillor's office in Bandar Perda at 10.30am before walking out some three hours later.
The MACC and several enforcement agencies also raided the factory Thursday, following complaints from villagers who feared fumes from the factory could affect their health.
The factory, which processes carbon filters, has been operating on agricultural land inside an oil palm estate for more than 10 years.
The operations against the illegal factory also involved officers from the Immigration Department, Department of Environment (DOE) and Inland Revenue Board (IRB).
