Police are conducting a search to seize valuables and documents in relation to 1MDB at the Langgak Duta private residence of former prime minister Najib Razak, a source said.
A man, who claimed to be a neighbour of Najib, was stopped by the police as he approached the house at 11.20 am on Thursday.
He said the family was cooperative.
"It's a big house so they had to search each room".
He later confirmed that no arrests have been made and no charges were mentioned by the authorities so far.
More than 10 police vehicles, including a truck, arrived at the house at 10.15pm on Wednesday after Najib had returned from attending "terawih" prayers at the Kampung Baru Mosque here.
