"Terminal 3 has been evacuated. A suspicious bag has been reported. Police are investigating," airport spokesperson Sisse Hansen told AFP.
"We are heading to a suspicious situation at Kastrup airport. Terminal 3 evacuated," police confirmed on Twitter.
The incident came just hours after Danish police raised the country's threat level by one notch to the second-highest level, citing the elevated risk of a terrorist attack after last week's Paris attacks.
