In the Netherlands, police is training eagles to grab rogue drones. In the United States, the Federal Aviation Administration requires the country's users to register their small unmanned aircraft with the government.

In India however, it is still illegal for civilians to use drones due to security threats. They are used by the government to monitor the country's borders and surveillance in conflict-ridden areas. Police in the city of Lucknow even planned to use drones to use pepper spray to control crowds.

The government has said that while it restricts the use of drones, it has not banned their import. In the absence of official guidelines, drones are often deployed for filming lavish weddings as well as Bollywood films. Chinese toy drones are also sold freely in several cities and online stores.

In the last couple of years, there have been numerous incidents of police investigating people flying drones. The Delhi Police were asked to monitor drone usage before India's Republic Day in January after an unidentified drone was spotted near the international airport in the Indian capital.

In Mumbai, police has been issuing a monthly order against using drones after a drone was found photographing the an atomic research centre in July. Since then, the police has maintained that terrorists can use paragliders and remote-controlled microlight aircraft for attacks.

Most recently, an American tourist was arrested for photographing the UNESCO World Heritage Site of Khajuraho with a drone camera without taking the government's permission.
