Mystery explosion was man attempting to hang curtains

A loud 'explosion' which sparked frantic police activity in Stockholm, Sweden, on Friday turned out to be nothing more than a man hanging curtains. Police and emergency services were called to investigate after witnesses reported the sound of a loud "explosion".

The mystery bang was heard at 11.40am around Brännkyrkagatan on Södermalm island, an area of the capital which is known for its range of trendy restaurants and hipster shops. The street was closed off while police investigated, but the cordons were lifted shortly thereafter when officers were unable to find the source of the alleged blast and there were no reports of injuries.
Nearby buildings and cars were checked but were not found to have been damaged. At the time, officers reported that one window on the street was broken, but did not believe it was connected to the incident. "The apartment owner had a broken window, it doesn't seem to be connected to any bang. He was at home himself putting up curtains," Näverberg said.

However, later in the afternoon it turned out that the apartment owner was in fact the source behind the mystery blast. The man had accidentally dropped a large drill when he was hanging up his curtains, which broke the window and fell on to a tin roof, causing the loud bang. Police were then called to the scene believing they had a hostage situation on their hands after witnesses reported seeing "a man in a window", mistaking his drill for "a gun-like object".
