A device exploded after being thrown into a restaurant in central Stockholm during the night, a Swedish police spokeswoman told dpa on Wednesday.

"We received a call that somebody had thrown a device into the restaurant," she said. "It was not open and nobody was injured, but
there were employees in the restaurant."

The spokeswoman was unable to say who had thrown the device. "We have technicians on the scene looking at what exactly was thrown inside."
