Local media has reported that the explosion was caused by a grenade, although this has not been confirmed by authorities. Officials also ruled out terrorism. "We do not know more than that", remarked fire department spokesman Lars-Ake Stevelind.
The explosion took place at about 11:00am just outside the Varby Gard subway station in Huddinge - a residential district in greater Stockholm, regional police spokesman Sven-Erik Olsson said.
According to the Local, "Explosives are often used by organised crime rings in Sweden, especially in the south where settling of scores and intimidation are frequent among drug traffickers".
The number of hand grenade attacks in Sweden almost tripled from ten in 2015 to 27 in 2016, according to local media.
