Odisha: The Odisha Police today detained four Russian nationals for flying a drone equipped with a camera capable of taking high-definition images over the Sri Jagannath Temple here, a senior police officer said.

Three of the four, who said they were members of ISKCON, were women, the officer added.

The shrine and its periphery areas were declared a "no flying zone" by the district administration in 2014 after a quadcopter took aerial videos and photographs of the temple and uploaded them to social media.

The around-the-clock patrolling team has also been deployed by the four towers surrounding the temple to prevent such incidents.

The four devotees from the International Society for Krishna Consciousness were operating the drone from the roof of the Radha Ballav mutt, close to the temple, the senior officer of the Singhadwar Police Station said.

They were questioned and then released on personal bonds, SP, Puri, Sarthak Sarangi, said.

"During questioning, they said that they were not aware of the 'no-flying' rules in the area and were trying to photograph the shrine for creating a roadmap to the place," he said.

They also said the map was primarily meant for a congregation in Puri next month of ISKCON devotees, Sarangi said, adding that all four had valid passports and visas.
