Danish capital hit by the second blast in four days.

An explosion has occurred outside a local police station in Copenhagen, according to law enforcement. The blast comes just days after an explosive device was detonated near a government office.

The explosion happened near a police station just outside the city center. According to local media, police are currently searching for a man spotted running from the scene. No injuries have been reported.

A video shows shattered windows and other damage to the front of the station.

On Tuesday, a blast outside the Danish Tax Agency’s office in Copenhagen injured one person. Police said the incident was the result of a deliberate attack.

Officials told Reuters that it was too early to say whether the two blasts are connected.
