Bride walks in on groom allegedly sexually assaulting bridesmaid

A bride in the US has allegedly walked in on her husband-to-be sexually assaulting one of her bridesmaids.

Daniel Carney, 30, from Pennsylvania, has reportedly been charged over the incident that happened just two days before the wedding.

It is understood the wedding still went ahead.

According to WNEP-TV, the bride-to-be walked in on the man sexually assaulting the bridesmaid who is thought to have been intoxicated at the time, falling unconscious and waking to the attack.

It is alleged that upon discovering the assault, the bride physically attacked the groom.

The wedding party and guests had gathered to celebrate the upcoming nuptials at the Shawnee Inn in Smithfield Township on August 30.

Carney allegedly pulled the woman into a downstairs locker room and attacked her. He has been charged with involuntary deviate sexual intercourse of an unconscious person and indecent assault.

Surveillance video of the incident allegedly shows Carney taking the victim who was "extremely unsteady on her feet" into the men's locker room.

The alleged victim blacked out from drinking and reportedly woke up in the locker room to the attack.

WNEP reports that a phone call following the alleged assault was intercepted by authorities. During the call, Carney allegedly repeatedly apologised to his accuser for the assault, blaming himself several times.

He also reportedly admitted to Monroe County District investigators that he assaulted the victim.

The man was charged on Thursday.
