One Russian driver's chances of making his F1 debut next year have taken a hit.
At Sochi, Formula 2 driver Artem Markelov admitted his chances of a 2019 race seat - ostensibly with Williams - was "50-50".
"I will find out in a month and a half," he said.
But those hopes have taken a serious hit.
During the race weekend, Markelov's wealthy father Valery was arrested by Russian authorities and detained.
Markelov senior, heading a large consortium linked to Russian Railways, is accused of bribing a government official to the tune of 2 billion rubles (US $30m).
"We are talking about one of the top officials of Russian Railways," a source told the Russian news agency Rosbalt.
Artem Markelov, 24, contested the Friday practice session for Renault in Russia last weekend.
