Temer, the predecessor of current President Jair Bolsonaro, was Brazil's most unpopular leader ever and faced a number of corruption accusations on leaving office last year.
Brazil's ex-president Michel Temer was arrested Thursday, becoming the latest former leader of the Latin American country caught up in a sprawling anti-corruption probe that has already claimed dozens of political and corporate scalps.
Police arrested Temer, the 78-year-old predecessor of current far-right President Jair Bolsonaro, in Sao Paulo, a spokesman for the federal prosecutor's office in Rio de Janeiro told AFP.
Former mines and energy minister Moreira Franco was also detained along with six others, including business people, Brazilian news site G1 reported.
Temer, Brazil's most unpopular leader ever, faced several corruption accusations on leaving office last year.
He escaped action over two of the allegations in 2017 when Brazil's Congress voted to dismiss them, cementing his reputation as the ultimate survivor in one of the world's messiest and scandal-ridden democracies.
But the third accusation was filed days before Bolsonaro's mandate started on January 1, leaving Congress with no time to evaluate the charge.
Launched in 2014, the Car Wash investigation uncovered a vast graft operation involving state oil firm Petrobras and major construction companies and bribes to politicians of several parties.
The scale of the corruption uncovered stunned Brazilians, who have grown weary of graft among their leaders.
Live coverage of arrests
Temer is just the latest former president caught up in the probe that has rocked Brazil's business and political elites.
The center-right politician took over as a caretaker figure after the last Workers Party president, Dilma Rousseff, was impeached and removed from office in 2016, accused of cooking the government's books.
While Rousseff was not directly implicated in the Car Wash scandal, she was damaged by an association having chaired the board at Petrobras between 2003-2010, when much of the alleged corruption was flourishing.
Former leftist president Luiz Inacio Lula da Silva is serving a lengthy jail term after being found guilty in two corruption cases.
Far-right leader Bolsonaro campaigned on a hard line against corruption and crime and his victory in October's election was in part attributed to the Car Wash investigation.
Temer did not contest the ballot.
The probe was originally overseen by Brazil's current justice minister, former judge Sergio Moro, who jailed Lula. He has been replaced by Gabriela Hardt.
Local TV channels broadcast live coverage of the latest arrests -- much to the delight of many viewers.
As president, Temer was deeply unpopular among ordinary Brazilians. Whenever he spoke on television, horn honking and pot banging could be heard in major cities like Rio de Janeiro and Sao Paulo.
He was booed loudly at Maracana stadium when he opened the 2016 Rio de Janeiro Olympics.
