A man who had threatened to set off explosives in the heart of Stockholm on Thursday, prompting an hours-long lockdown in the Swedish capital, finally gave himself up to police. Police sealed off large parts of the city and evacuated buildings as they negotiated with the man holed up inside a building near the headquarters of the main ruling political party, the Moderates, saying he was carrying explosives.
