98-year-old ex-Malaysian PM Mahathir Mohamad's sons under MACC investigation aided by offshore business records.

98-year-old former Malaysian Prime Minister Mahathir Mohamad is reportedly under investigation by the country's anti-corruption agency, the Malaysian Anti-Corruption Commission (MACC). His two eldest sons, Mokhzani and Mirzan Mahathir, have been ordered to assist with the probe. The investigation is believed to be linked to offshore business records revealed by a journalism consortium. The brothers have received two extensions on the original February deadline for compliance.
