"The police issued an administrative offence warning to him."
He said the Australian man had come to Russia to attend the games of the ongoing FIFA World Cup.
The police booked him for an administrative offence under Article 11.4 of the Code for Administrative Offences (Encroachment on the rules for operations in airspace) and set him free but the quadcopter was confiscated.
The Australian faces an administrative fine of 5,000 rubles ($80.6).
