A phone call was made to Skåne police just after 11am on Saturday when the caller issued bomb threats to four addresses in the region.
According to the Sydsvenskan newspaper the conversation included detailed information and named police staff and a prosecutor who the caller said would be blown up.
Bomb disposal experts were called in to inspect homes in Trelleborg, Vintrie, Skegrie and Tygelsjö and around 20 people were evacuated in the process.
”We took the calls seriously and cordoned off the buildings while bomb specialists investigated the areas,” Skåne police spokesperson Mikael Persson, told news agency TT.
A device was found at an apartment in Trelleborg but after an initial inspection police concluded it was neither charged or suspicious.
No further devices were found in connection with the investigation and evacuees were able to return to their homes late in the afternoon.
Sydsvenskan reports that motive behind the bomb is related to a recent court case in which the 34-year old was a complainant left dissatisfied with the verdict when the defendant was freed without charge.
Another man taken in for questioning was release by police on Saturday evening.
Although police believe the threats were serious, the homes will not remain under guard.
”At the moment we don’t have any reason to require such measures,” said officer Sven-Åke Johansson from Ystad police.
