The brother of the Bethpage man accused of killing his wife is now behind bars.

Thomas Walsh was arrested Monday at the Nassau County Correctional Center. Officers say he started a fight with jail guards when he tried to visit his brother outside of visiting hours.

Thomas Walsh was held overnight at the 3rd precinct before he faced a judge Tuesday. He was arraigned on charges of criminal trespassing, obstructing governmental administration and resisting arrest.

Walsh, police said, is the brother of William Walsh, who's accused of strangling his wife during a fight about allegations he cheated on her and then trying to make it look as though she was a victim of random roadside violence.

Special education teacher Leah Walsh's body was found along a highway last week.

William Walsh says he didn't kill his wife. He's applied for a court-appointed attorney as he fights a murder charge.Thomas Walsh will be back in court on Thursday. If convicted, he faces a year behind bars.
