Krudttønden: Undersøgelse afsluttet. Intet om sprængstoffer. Afspærring ophævet #politidk— Københavns Politi (@KobenhavnPoliti) 17 февраля 2015
The Copenhagen police confirmed to Sputnik news agency earlier that a suspicious letter was found outside Krudttonden cafe in downtown Copenhagen on Tuesday morning, raising security concerns. A bomb squad was dispatched to the area to investigate the finding.
On Sunday, the same shooter murdered a man and injured two in an attack on a synagogue in the Danish capital.
Police investigate the theory that the gunman was inspired by a series of gun massacres in France last month, including at a kosher store, which claimed the lives of 17 people.
