It was witnesses who alerted the police when they saw the ongoing theft. Just a little while later, police were able to arrest the three suspected men as they drove in a car in Oskarshamn.
The car contained suspected theft and the men were arrested during the night.
"You can suspect that this is a foreign league," says Christer Karlsson, on-duty investigative leader at the Kalmar police.
The value of what was stolen is still unknown.
