“He has the sort of injuries that make one suspect a crime has been committed. A preliminary investigation into murder has been launched,” Stockholm police spokesperson Anders Jönsson told the TT news agency.

Police at first were unable to identify the man, who was found near a road in the Glömsta neighbourhood of Huddinge, south of Stockholm.

“He’s 30 years old. The man isn’t known to us from any previous incident,” said Ulf Janzén of Stockholm’s southern district police to TT.

By Sunday afternoon, police had determined the man was a Polish national, the Expressen newspaper reported.

“He’s not in any of our registries,” Janzén told the newspaper.

Forensic specialists spent Sunday examining the site where the man was found, although police suspect that his body was dumped there over night.

“We think the crime scene is somewhere else,” Janzén told TT.

Police were alerted shortly after 9am Sunday morning that a man was lying lifeless near Bergavägen. When police arrived on the scene, the ascertained that the man was dead and that he may have been the victim of a crime.

“I don’t want to comment on what sort of injuries he had,” said Jönsson.
