OSLO, April 9 (Xinhua) -- A Russian young man has been charged with illegal dealings with explosive material after police carried out a controlled explosion of what they described as a bomb-like object in central Oslo early Sunday, Norway's police security service (PST) said.
The Norwegian police also raised the country's threat level to "probable" from "possible," which is valid for two months, PST head Benedicte Bjornland told a press conference.
The 17-year-old Russian citizen, who came to Norway as an asylum seeker in 2010, was taken into police custody with an improvised explosive device in Oslo's Gronland area late Saturday, PST police attorney Signe Aalling said at the same press conference.
Police carried out the controlled explosion of what they described as a bomb-like object early Sunday after the object was found around the Gronland subway station in central Oslo late Saturday and a large area was cordoned off.
The cordon was lifted early Sunday and the Gronland area resumed normal activities.
