The former lead singer of punk rock band Mest was arrested on suspicion of fatally stabbing a 25-year-old man during an argument, police said.

Anthony Lovato, 26, was being held on $1 million bail pending an investigation of criminal homicide, said Officer Mike Lopez of the Los Angeles Police Department.

Lovato and another man argued early Sunday in the parking structure of an apartment building, Lopez said. When police arrived at the scene, they found the unidentified man lying on the ground with knife wounds. He died later at a hospital.

Lt. Andrew Neiman said Lovato was calm and cooperative when police arrived.

"He did in fact call the police, call 911, after the incident and remained on the scene (to) surrender himself," he said.

Authorities said police had been called to a woman's apartment Saturday night when the two men fought, but no one was arrested at that time. They said Lovato and the victim had been involved with the woman at different times.

Lovato and his brother Matt formed Mest in 1995 in suburban Chicago and recorded several albums on Madonna's Maverick label. They performed on the Warped Tour, a touring music and extreme sports festival, in 2003.

The band broke up last year.
