An explosion occurred outside a local police station in Copenhagen, police said, in the second blast to hit the Danish capital in four days.
No one was injured in the blast, which happened outside a mobile police station in the Norrebro, just outside the city center, police said.
On Tuesday, one person was slightly injured in an explosion outside the Danish Tax Agency’s office in Copenhagen, in what police said was a deliberate attack.
Police told Reuters it was too early to say whether the two blasts were connected, but could not immediately comment further.
Police were searching for a man running from the scene of the blast, Ekstra Bladet said.
Serious attacks or violence are rare in the small Nordic country of 5.7 million people that prides itself on a reputation for safety and social tolerance.
