It was at a joint supervision of the police, the Environment Office and the rescue service in St Jakobkyrkans party room in May last year that the inspectors noted that the alcohol at the wedding party was not from Sweden.

"When the parties are held on a party floor, the alcohol should be bought at Systembolaget or another supplier, it is in the condition," Jonas Packén, a police officer who is one of the responsible for the control of the party floors, told SVT then.

Samples later showed that the alcohol was blended with homegrown technical spirits.

Now the groom is being convicted of illegal sale of alcohol and SEK 1,000 in daily fines, which the county newspaper was the first to report.

The grant was the first of many attending wedding parties in Södertälje. The main purpose was to get the party floor owners to apply for a permanent serving permit. This would mean that the banquet halls are responsible for the liquor purchases - instead of the fact that, as it was then, every single bridal couple had a temporary alcohol permit.

And according to the police, there has been an improvement since the controls of the banquet halls.

- It was basically just system booze what we saw during our checks, Jonas Packalén tells LT.

Of a total of eleven banquet halls, three will have temporary permits while seven are expected to be granted shortly.
