A couple's happy day turned violent Saturday when a guest at the hotel hosting their wedding came at the bride with a sword, Sussex County officials said.

The bride, whose name is currently being withheld, suffered a non-life-threatening cut on her left arm.

The bride and her bridal party were celebrating her wedding Saturday at the Grand Cascades Lodge in Hardyston, when the incident occurred, First Assistant Prosecutor Gregory Mueller said.

In a hallway of the hotel, Carlos Mejia, a 43-year-old hedge fund manager in New York City who was at the hotel for business, allegedly approached the group and asked if they had a cigarette to spare.

When the bridal party said they didn't have a cigarette, or wouldn't give him one, a verbal fight started, Mueller said. Police reported that witnesses observed Mejia yelling obscenities before heading back to his hotel room.

Mueller said the bridal party knocked on his door and yelled at Mejia through the door. When he swung it open, he allegedly emerged with a sword in his hand, police said.

Mejia began swinging the sword at the bridal party and threatened to kill her. Mejia allegedly then swung the sword and slashed the bride's arm.

Hotel security detained Mejia until police arrived, and he was disarmed by several guests, Mueller said.

Witnesses at the hotel told police that he had been seen walking around the hotel with the sword before the fight, and police reports show that an officer present noted Mejia appeared to be under the influence of either drugs or alcohol.

Mueller told NJ Advance Media that the prosecutor's office has never seen an incident like this one before.

"It's a really unique case," he said Wednesday.

Mejia now faces a third-degree aggravated assault with bodily injury charge, a charge of third-degree terroristic threats, a third-degree weapon possession charge and a disorderly persons offense of harassment.

Mueller said Mejia was released from jail Tuesday, on certain conditions, pending his trial.

The details of how he came to interact with members of the wedding party and the incident itself are still under investigation.
