Arlanda Airport in Sweden faced another drone scare late Monday night, causing minor flight delays.

This incident follows a similar event the previous night, which led to a temporary halt in air traffic.

Police were dispatched to the scene after a security guard spotted a drone over one of the runways.

The drone was seen leaving the area, prompting an ongoing investigation into potential violations of aviation and protection laws.

No arrests have been made yet.

Experts suggest the drone flights might be deliberate attempts to test the airport's security readiness.

Swedavia, the airport operator, advises travelers to check their website for updates on departures and arrivals.
