A wedding celebration in Vienna’s 21st district was abruptly interrupted after officers from the financial police uncovered a network of illegal workers, despite their efforts to blend in.

Around 35 financial police officers, alongside regular police and officials from the Federal Office for Immigration and Asylum, were called to the scene following an anonymous tip-off, according to a press release.

After some initial challenges in identifying the individuals involved, authorities detained 22 Serbian nationals who were found to be working illegally. The workers had been bussed in from Serbia and were employed in various roles, including in the kitchen, banquet hall and decorating the venue.

The financial police reported that the workers claimed to be relatives of the bride and groom, and denied any involvement in the event’s operations.

Further investigation uncovered 26 breaches of social security regulations, while two individuals were reported for welfare fraud. These workers had been engaged in undeclared work while also claiming social benefits such as income support and unemployment benefits.

Finance Minister Magnus Brunner condemned the practices, stating: “Even the most romantic celebrations need proper accounting. Tackling illegal employment is a top priority for us. This operation demonstrates our commitment to combating undeclared work and fraud. We will take all necessary steps to protect the integrity of our labour market.”

Under Austrian law, employers who hire illegal workers face fines ranging from €2,000 to €20,000 per employee, while penalties for undeclared work range from €730 to €2,180 per worker. Offenders involved in welfare fraud can face prison sentences of up to three years.
