The barriers surrounding the bomb-threatened restaurant have now been lifted.

“The forensic team found explosives but no ignition device. As far as I can tell, there was no danger to the public,” said the Uppsala police force’s spokesman Christer Nordström to news agency TT.

Forensic technicians took the suspicious object with them for further analysis.

The restaurant was subjected to arson earlier this summer. At present, the Uppsala police have no suspects for the bomb threat.

“But obviously we suspect that it’s connected to the fire,” said Nordström.

Four men were arrested last week, suspected of attempted extortion against the restaurant, which is located in Uppsala’s city centre. The men, between 18 and 29 years old, are well-known by the Uppsala police force, and were arrested for the crime on probable cause, the highest level of suspicion.

The extortion allegedly occurred between the 2nd and 9th of August, and police believe that the arson attack against the restaurant, on August 5th, is connected with the extortion attempt.

Suspected bombs are reported to the Security Police’s bomb data central, which also receives reports of bomb threats and military grenades found.

Roughly 250-300 incidents are reported to the central every year, of which between 25 and 30 are live events, where a bomb has been found or detonated.
