It was not clear if the action was an attempted militant attack or had some other motivation.

After the explosion, security personnel surrounded the suspect in a park and removed a bag wrapped around his waist with remote controlled cutting pliers.

He was taken to hospital with injuries to his face and arm which probably stemmed from the small explosion, a Copenhagen police spokesman said.

“A massive investigation is now being undertaken but it is still too early to say if it is a terror-related crime or another form of criminal activity,” the chief of Danish Security and Intelligence Service (PET), Jakon Scharf, said.

The bomb exploded in a cellar under the Hotel Jorgensen in central Copenhagen. The suspect fled but was caught by police in nearby Orsted park after they sealed off several streets.

“There was a bag nearby the suspect. It was shot at without exploding. So apparently there were no explosives in the bag,” the police spokesman said.

Police were trying to confirm the identity of the man, who lay on the ground for hours while surrounded by police in the Orsted park before being taken to hospital.

“The justice ministry has informed civil servants that it doesn’t seem to be an ‘Islamist’ or a ‘person with terror plans’ but that the person in question may possibly have been planning ‘another criminal act’,” daily Berlingske Tidende reported on its website.

Several streets around the hotel and park were still sealed off late Friday.

There were no other injuries, Danish media reported.
