A fleet of supercars said to have been seized by the Swiss authorities in a money-laundering investigation involving the son of the leader of Equatorial Guinea was auctioned on Sunday in Switzerland.

The vehicles were among 25 luxury cars sold for more than $27 million at Bonhams auction house, according to The Associated Press, in what Bonhams called a “very special sale.” Beforehand, the cars had been estimated to bring in more than 12 million euros, or $13 million.
