The anti-crime package, which was approved by Brazil’s Senate earlier this month, toughens laws to tackle corruption, organised crime and violent crime practiced by criminal gangs.

It also simplifies sentencing in some cases.

The package was a major promise by Bolsonaro, a former army captain who surged to power last year on a campaign vowing to end years of corruption and spiralling violent crime.

Brazil has the world’s highest number of murders.

“The final text that has been sanctioned by the President brings progress to the anti-crime legislation in the country,” Justice Minister Sergio Moro said in a statement early on Wednesday.

Moro, a former judge who made his name jailing scores of Brazil’s business and political elite in the “Operation Car Wash” investigation during the past five years, said Bolsonaro adopted several vetoes suggested by the Ministry of Justice.

Among the vetoes by the right-wing president was a provision to triple the sentence when a crime is committed or displayed in social networks.

The bill eliminates the restriction on the collection of genetic material only in cases of wilful crime committed against life, sexual freedom or sexual crime.

Bolsonaro, who ran on a law-and-order platform, won support from Brazilians tired of the warring drug gangs that have come to terrorise large swaths of the country.
