The Committee of Inquiry (COI) will submit its findings to Deputy Prime Minister and Home Affairs Minister Teo Chee Hean.
Teo has granted the committee a two-week extension to the original June 13 deadline so that it can go through testimonies and other relevant information, reported The Straits Times today.
The COI Secretariat said in a statement today that following the conclusion of the public hearing on March 26, the committee has conducted "further inquiry".
The committee was presided over by a four-man panel chaired by former Supreme Court Judge G Pannir Selvam.
