The mother-in-law of Bernie Ecclestone has been freed after being kidnapped in Brazil last month, according to local media.

Aparecida Schunck was taken from her home in Interlagos, San Paolo, with her captors demanding $36.5 million in ransom.

The 67-year-old is the mother of Ecclestone's wife, Fabiana Flosi, whom the entrepreneur married in 2012 - three years after meeting her at the Brazilian Grand Prix.

Their marriage followed Ecclestone's divorce from his then wife of 25 years, Croatian model Slavica Radic.

Globo News reported that Mrs Schunck was found at a home in Sao Paolo on Sunday night after a police operation.

No ransom was paid, according to police.

"She is in good health (and) two people have been arrested," the head of the Sao Paolo police, Elisabete Sato, said.
