LOS ANGELES — A man who allegedly opened fire on a crowd at

an Isley Brothers concert in Los Angeles late Friday night was shot to

death by a police officer on the scene, authorities said.

Three others also suffered gunshot wounds in the incident that happened

just before 11 p.m. at Los Angeles Sports Arena. Police spokesperson Jason Lee could not confirm whether those victims had been shot by the suspect or by the officer. The names of the victims and the officer have not been released.

Lee said an on-duty officer assigned to the arena witnessed a man firing a gun at the crowd inside the venue. The Isley Brothers were onstage performing at the time.

The officer identified himself and fired at the suspect, who turned and

pointed his gun at the officer, according to the spokesperson. "In fear

for his own life, the officer returned fire," Lee said, reading from a

statement.

The suspect was pronounced dead at the scene. Two of the surviving victims were treated and released, while the third remains hospitalized in serious condition.

The Isley Brothers' hits include "It's Your Thing" (RealAudio excerpt), "Twist and Shout" and "That Lady" (RealAudio excerpt). The Cincinnati-born family group rose to fame in the late '50s.
