Former Malaysian Prime Minister Najib Razak has been arrested in Kuala Lumpur, state media reported, as part of a probe into alleged theft and money laundering at the 1MDB state investment fund.
Allegations over the misappropriation of state funds at 1MBD emerged in 2015 as the public learned that $4bn had gone missing from the fund and nearly $700m was allegedly transferred into Najib's bank account.
Malaysia's Prime Minister Mahathir Mohamad says that authorities have an "almost perfect case" against Najib and his allies.
