A man was killed outside a Stockholm subway station Sunday morning when an object he picked up from the ground blew up, local reports said.
A 45-year-old woman was also injured in the blast outside the Varby Gard station in Sweden’s capital, The Local reported.
“There was something on the ground that the man picked up and then it exploded,” said Stockholm Police spokesman Sven Erik Olsson.
Police said they didn’t believe the 60-year-old man and the woman were purposefully targeted by whoever left the explosive but were investigating.
“There is obviously something that has exploded strongly …But we will have to wait for the technical investigation,” a police spokesman said.
Local paper Aftonbladet reported the device was a hand grenade, but police weren’t commenting on the nature of the device.
