"The version of the incident in RUS TV did not show at all the manipulative and provocative method of the russian state TV Crew in Cologne. How would you react when people don't stop to film next to your sleeping room? And shoot illegally items in other rooms? And refuse to go? I realised too late that it was an attempt by the RUS reporter to provoke an incident. They fled when they realised I'm calling the police," Seppelt said on his Twitter account.
He added that police ordered him to follow the crew to report the place of their destination.
According to Seppelt, visit of Russia's TV crew was a "perfidious" attempt to discredit and undermine the anti-doping research.
In December 2014, ARD released a film titled "The Doping Secret: How Russia Creates Champions" on alleged doping abuse and corruption in Russian sports. The second installment of the film followed on December 7, the third was released on March 6, 2016 and the fourth one was released on Thursday.
Following the release of the film, the World Anti-Doping Agency (WADA) launched an investigation into the allegations of doping abuse in Russian sports. In November 2015, WADA's Independent Commission issued a report accusing Russia of numerous breaches of global anti-doping regulations. As a result, the International Association of Athletics Federations (IAAF) temporarily suspended the Russian Athletic Federation's membership.
The Russian authorities have promised to carry out a clean-up program to fulfill the WADA demands in order for the country's athletes to be allowed to participate in the 2016 Olympics.
