Markelov Snr's troubles come just days after his son's official F1 debut which took place last weekend at Sochi when the 24-year-old F2 racer was entrusted with a run in Friday's FP1 session.
A co-owner of a the 1520 Group involved in the design and construction of railways in Russia, Markelov is accused by the Basmanny Court of Moscow of bribing a government official to the tune of 2 billion rubles (US $30m). He is expected to remain in custody until at least December 1.
Since its inception, Artem Markelov's career in motorsport has been funded in large part by his father, with logos of the 1520 Group appearing this year on the flanks of the driver's Russian Time F2 car.
In Sochi, Artem Markelov rated his chances of racing in F1 next season at 50/50, admitting to being in discussion with Williams for a seat with the Grove-based outfit.
"I will find out in a month and a half," the young driver said in Russia.
It is not known however what impact his father's affairs will have on his racing ambitions.
With two rounds to go, Markelov is current fifth in the FIA F2 Championship's standings.
