Mokhzani could not immediately be reached for comment. His father, who served two stints as prime minister, has alleged the probe is politically motivated.
The order is part of MACC’s investigation into information from leaks of offshore business records that were revealed in recent years by the International Consortium of Investigative Journalists, a global media network.

Malaysia’s Mahathir slams Anwar over corruption probe against son Mirzan
Mirzan is a director of several companies, including Philippine oil and gas company Petron and its parent company San Miguel.
In 1998, the Post reported that cash-stricken Mirzan sold off his Hong Kong-Malaysian liquidised natural gas company to state-owned Petronas, a move seen as a father-son bailout, as Petronas answers directly to the prime minister – Mahathir.
Aside from Mirzan, his brother Mokhzani also made his fortune off oil and gas, with Forbes naming him as one of Malaysia’s 50 richest people in 2020.
Mahathir has long maintained that his children’s fortunes have been legitimately made.
Anwar has laughed off talk of a conspiracy to take down his rivals.
