A justice at Brazil's Federal Supreme Court has delivered the bulk of an investigation to the country's top prosecutor into allegations that President Michel Temer took bribes in exchange for political favors doled out to meatpacker JBS SA.
The office of Justice Edson Fachin said it sent a copy of the probe to Prosecutor-General Rodrigo Janot on Thursday.
Janot will have five days to lodge formal charges against Temer.
Under Brazilian law, the probe has to be overseen by Fachin, who approved the graft probe into Temer in May.
The allegations are based on plea-bargain testimony from members of the family that controls JBS, who said they paid Temer at least US$4.6 million in bribes since at least 2010 to help win lucrative government contracts, resolve tax disputes with the government and help obtain free loans from state development bank BNDES.
The five-day deadline stems from the potential expiration of the preventive detention of a former Temer aide who was accused of receiving bribes on behalf of the president.
Temer has repeatedly denied any wrongdoing.
Reuters news agency says its efforts to contact Temer's lawyer for comments were unsuccessful.
Just weeks ago, Temer was acquitted of financial irregularities in the 2014 election campaign in which he ran as vice president.
That ruling came just a day before he was forced to deny further damaging allegations, when an article in Veja magazine claimed that the country's secret security service, known as Abin, had spied on Justice Edson Fachin.
