Authorities say a North Texas man is dead after shooting himself at a mall where he went to confront someone.
    
Lewisville police said no one else was injured.
    
Police said they were called to the Vista Ridge Mall about 4 p.m. Monday after reports of an argument between a woman working at a kiosk and someone described as a male acquaintance who had confronted her.
    
Police spokesman Capt. Kevin Deaver said the man pulled a handgun and shot himself when mall security tried to escort him outside.
    
The man was pronounced dead at a hospital. His name was not immediately released.
    
The mall was not evacuated but parts remained closed after the shooting as police were investigating.
    
Lewisville is 20 miles northwest of Dallas.
