Putrajaya - Plainclothes police officers are raiding a house in Precinct 10, believed to be in connection with the 1MDB case.
The officers, from the Bukit Aman Commercial Crime department, have been at the house since 1pm.
Several boxes have been seen removed from the house and put into a white van which bore no police credentials.
The house is only 200m from Seri Perdana and belongs to the Property management Division of the Prime Minister's Department.
An online portal described it allegedly as Datuk Seri Najib Tun Razak's "safe house".
