Danish police are investigating threats directed at air traffic at Copenhagen Airport on Friday, a day after a series of hoax bomb threats caused significant disruption across Europe. Authorities stated that their initial assessment indicated no danger to passengers.

"We are once again at Copenhagen Airport today in connection with threats directed at air traffic," police said in a statement. "We are now investigating the incident and have a visible presence at the airport."

The investigation comes in the wake of multiple bomb threats that have disrupted passenger flights across the continent in recent days. These incidents have led to diversions, emergency landings, and security sweeps, though no explosives have been found.

On Thursday, at least 27 flights were affected, including several originating from the UK. A Ryanair flight from London to Bulgaria was among those targeted, and other planes required escort by fighter jets as they were diverted. Bomb squads were deployed to inspect aircraft upon landing.

An Aer Lingus flight from Dublin to France, and two flights bound for Prague from Newcastle and Glasgow, were also subjected to bomb threats. These flights have since landed safely. British airports, including Heathrow and Birmingham, confirmed receiving threats that were subsequently resolved, allowing flights to proceed.

Heathrow Airport declared the threats it received as not credible, according to The Times.
