What was supposed to be the happiest day of her life ended with flashing lights, handcuffs and a jail cell.

A 42-year-old bride in Poland was arrested while still wearing her wedding dress after police say she attacked her own mother during a wild wedding reception that spiraled completely out of control.

According to authorities in the city of Suwałki, officers rushed to the scene after reports of a violent fight breaking out during the celebration. By the time police arrived, the bride and her mother were allegedly in the middle of a screaming match that quickly turned physical.

Police said the argument exploded into a full-blown brawl after a “heated exchange of words” between the two women. Investigators did not reveal what sparked the family meltdown, but officers claim the bride repeatedly struck her mother and even knocked her to the floor during the chaos.

Shocking photos released by police show the bride still dressed in her white wedding gown as officers placed her in handcuffs and marched her away from the reception. In one image, the newlywed can be seen with her hands cuffed behind her back while being escorted to a jail cell by police.

Authorities said the bride was taken into custody because she allegedly posed “a direct threat” to her mother.

Things reportedly got even uglier after police performed a sobriety test on the bride. Officers said she had an extremely high blood alcohol level of nearly 0.15%, a level associated with slurred speech, impaired judgment and poor coordination.

Paramedics treated the bride’s mother at the scene following the alleged attack, though officials have not revealed the extent of her injuries.

As if the wedding disaster wasn’t already unbelievable enough, police also issued the bride a restraining order banning her from contacting her mother for 14 days after the violent confrontation.

The bizarre family drama is still under investigation, according to local authorities.

One minute she was cutting the wedding cake — the next she was heading to jail in a wedding dress.
