Former Malaysian Prime Minister Najib Razak was arrested Tuesday according to Malaysian state media Bernama.
Razak is the subject of a corruption investigation after billions of dollars went missing from a state investment fund that he set up.
Malaysian police say they have seized almost $275 million worth of jewellery, handbags, watches and cash from premises linked to Najib, while authorities have frozen more than 400 bank accounts as part of the 1MDB probe.
Najib denies any wrongdoing.
This story is developing.
Rosmah and Najib were probed as part of the investigation into former 1MDB subsidiary, SRC International, and some RM42 million that was channelled into Najib's personal bank account.
Malaysian investigators are questioning the producer of The Wolf of Wall Street as they step up efforts to recoup funds potentially lost through 1MDB. Until their shock defeat in May, Najib's party and its coalition allies had run Malaysia for six decades.More news: Chris Froome Set To Be Banned From Tour De France

The Star reported that Najib was arrested at his home in Langgak Duta at around 3pm today.
"They came in three to four unmarked cars", the source, a senior security official familiar with the arrest, said.
Asked if and when Najib would be detained by police, Fuzi said he could not provide such information.
He is due in a Kuala Lumpur court at 8:30 a.m. local time on Wednesday, where he will be charged, Goh added.
Najib's stepson only leaves MACC office at 10.30pm.
The 1MDB government task force this week said 408 bank accounts involving funds of almost 1.1 billion ringgit had been frozen.
The civil suit against Red Granite was part of an effort to recover some of the $4.5 billion that US prosecutors say was stolen from 1MDB. "It is long delayed as the scandal has turned Malaysia into a global kleptocracy country", he told AFP. The new Attorney-General Mohamed Apandi Ali cleared Najib in 2016, saying the money was a donation from the Saudi royal family and that most of it was returned. "Let the rule of law take place".
