STOCKHOLM, June 8 (Xinhua) -- Police are investigating several leads after a powerful explosion in southern Sweden on Friday morning was found to be deliberate, reported Swedish news SVT on Saturday.
The explosion, which injured several people and damaged over 200 apartments in the city of Linkoping, appears to have been caused deliberately, police said during a press conference Friday. So far there is no suspect and police are following leads as well as seeking tips from the public.
"We suspect that someone has placed an explosive charge just outside one of the properties, but we do not know exactly when this has happened," Bjorn Oberg, police press officer, told SVT.
There has been speculation of gang violence, according to SVT, but police have refused to comment on any of the leads currently being investigated. The police's national operational department is assisting local police.
Approximately 250 apartments suffered severe damage, SVT reported. Some parts of the area remain blocked off while the forensic investigation continues.
In total, seven people were taken to hospital Friday with mild to moderate injuries. Two of them are currently still under observation.
