HOUSTON – We have a bizarre story that happened overnight in Katy. One man says he had to grab a sword in a duel with his girlfriend's estranged husband.

"Swords and flower pots; it sounds nuts, he is psycho," said Eugene Thompson, the homeowner's boyfriend.

According to deputies with the Harris County Sheriff's Office, Thompson lives at a home with his girlfriend and said Saturday night they got into an argument. That's when his girlfriend called her estranged husband, who stopped by the house around 10 p.m.

"It's late, I get up and look and he is here, and I am like go away, you don't live here anymore," said Thompson.

Thompson's girlfriend let the man inside. Thompson said he ran to the back bedroom and told the man to leave the house, but he refused and started charging at him. That's when Thompson says he grabbed his replica master sword from 'The Legend of Zelda.'

"I heard him heading to the bedroom where I was, so I jumped in the closet and I grabbed one of my replica swords, and I pulled it out and stood at the doorway, and he was coming down the hallway at me while I was yelling, 'Go away, you don't live here' and he just walked right into the point of the sword, I don't know if he thought it was a toy," said Thompson.

Thompson told Local 2 he managed to get the man out of the house and locked the door. But he said the man wouldn't give up and broke through the front door and ran back into the house.

Deputies said the two men fought over the sword and in the scuffle, the estranged husband was stabbed -- once in the chest and once in the leg. Thompson said the man grabbed a flower pot from outside and smashed it over his head.

"It dinged me on the head and all of a sudden I had blood pouring down my face," said Thompson.

Deputies arrived and took the estranged husband to Memorial Hermann Hospital in serious condition.

Thompson was transported to another hospital to get the gash in his head stitched up. Thompson said now he's trying to figure out what to do.

"I am just trying to figure out what to do from here. I have to find a new place to live," said Thompson.

Thompson's girlfriend was not injured in the fight.
