KUALA LUMPUR: A police team from Bukit Aman's Commercial Crime Investigation Department raided the office of accounting firm Deloitte here at Taman Tun Dr Ismail.

The team, comprising over a dozen plain clothes and uniformed police personnel, arrived at the office tower here at around 10.45am on Thursday (May 23) in three unmarked police cars before making their way to the offices on the 16th floor.

Several police personnel could be seen walking in and out of the lobby of the building to where their vehicles were parked.

Deloitte is believed to be the first firm to be raided by Federal police in its investigations into the 1Malaysia Development Berhad (1MDB) scandal.

It is among the "Big Four" international accounting companies that include Ernst and Young, KPMG and PricewaterhouseCoopers.

Deloitte was appointed the auditor for 1MDB Real Estate Sdn Bhd between Mac 31, 2015 and 2016.

Deputy Inspector-General of Police, Datuk Mazlan Mansor, when contacted confirmed the raid.

"I can confirm that we have raided the firm and seized documents to help with our probe into the 1MDB case.

"A team from the Bukit Aman CCID conducted the raid, in line with their ongoing investigations into the case," he said, adding that no arrests were made during the raid.

The police team was seen exiting the building and heading for the loading bay at the lower ground floor at around 5.30pm.

They were sighted loading two cardboard boxes into an unmarked police car and a police van there before the van went down to the basement level. 

An additional nine boxes were loaded into the van there.

They left the building at around 5.55pm.

Deloitte Malaysia responded to queries from The Star, saying that police arrived at the offices seeking assistance in the provision of records relating to 1MDB.
