Nine elderly people were the recipients of the 24 packages.
Security personnel at Postnord reacted, exactly to what the police do not want to say, and went to the address where the packages were to be delivered in Västerås.
There they grabbed a man.
Postnord suspects that other people ordered the packages for themselves in the names of the elderly people.
The 24 packages should not contain anything dangerous but have a high value, according to police spokesman Daniel Wikdahl.
- The estimated value of four packages you looked at yesterday was SEK 20,000.
If it is the same value in the rest of the 20 packages, it can be a lot, he says.
The arrested man, who is in his 20s, was later arrested.
Another man of the same age has also been arrested.
They are suspected of fraud.
