The sons of multimillionaire Telman Ismailov were two of the drivers said to have been involved in a luxury-car race in Switzerland that ended in a crash leaving an elderly German badly injured, media reported Tuesday.

Alekper and Sarkhan Ismailov were steering the $1.9 million Bugatti Veyron and the $670,000 Mercedes SLR McLaren along Lake Geneva late Thursday when a third participant crashed a Lamborghini Murcielago into a Volkswagen, Kommersant reported, citing a source in the Swiss police.

The name of the Lamborghini’s driver has not been revealed because he is the son of a high-ranking Russian government official, the report said.

Itar-Tass on Tuesday identified the Lamborghini driver as a certain Babayev and said someone named Mironov was among the drivers. The agency cited Swiss paper Tribune de Geneve, yet as of Tuesday evening the paper had not published names on its web site. Eric Hoesli, a publications director at the newspaper, confirmed the name Babayev to The Moscow Times in e-mailed comments late Tuesday.

The Foreign Ministry spokesman Andrei Nesterenko confirmed that four Russian citizens were questioned in connection with the accident and released on bail, Interfax reported.

Asked about the drivers’ identities, Geneva police spokesman Patrick Pulh told The Moscow Times that he could only say they were all Russian citizens, male and between 20 years old and 24 years old.

The Lamborghini’s driver was a Geneva resident, he said. A fifth man, also in the car, had Swiss citizenship. All were released after questioning, and the investigation is ongoing, Pulh said.

A spokesman for Federation Council Speaker Sergei Mironov told Radio Mayak that his son was in Moscow and not involved in the race. Mironov is a relatively common surname in Russia.

The crash has roused considerable media attention and even caused Dmitry Rogozin, the Kremlin’s outspoken envoy to NATO, to lambaste the behavior of the country’s “golden youth.”

Swiss media reported that the driver was found to have a blood-alcohol level of 0.11 percent, well above the legal limit of 0.05 percent. He was part of a group of four cars speeding along the Geneva-Lausanne road. The accident happened when he was trying to catch up with his friends after he was forced to stop at a red light, the reports said.

He hit a Volkswagen driving in front of him, injuring a 70-year-old German man so badly that police have still been unable to question him. After the accident, the Russians rushed back, rescued the Lamborghini’s two passengers and drove away. They were soon tracked down by police and questioned.

When questioned by police as eyewitnesses, the Ismailov brothers said they did not know the Lamborghini’s driver and had just helped him to get out of the car after noticing the accident, Kommersant reported.

Swiss media reports said they did not care for the injured Volkswagen driver.

The fact that his sons were linked to a high-profile act of decadence comes as the latest blow to Telman Ismailov, who lost a significant part of his Moscow business this year.

He came under fire this summer when the government forced the closure of the massive Cherkizovsky Market, controlled by his AST Group, for alleged safety violations.

The bust came after Prime Minister Vladimir Putin criticized law enforcement for being complacent on smuggling, prompting speculation that it was an attack on Ismailov, in part because of his lavish spending abroad. Weeks earlier, the Azerbaijan-born businessman threw a sumptuous party at the opening of a luxury resort on Turkey’s Mediterranean coast, which was attended by many prominent Muscovites.

Ismailov is believed to be in Turkey.

Geneva’s La Tribune paper reported on its web site Tuesday that three of the Russian drivers have flown to Istanbul in a private jet. The report said they left Geneva on Sunday.
