An 11-year-old girl is dead following an after school fight at a Long Beach elementary school, but authorities say they have no immediate plans for arrests.

Police said Saturday night that the girl died at a hospital hours after the fight with another 11-year-old girl outside the school.

Authorities say Friday's fight didn't appear to be especially serious or violent, no weapons were used and neither girl was knocked to the ground.

But Deputy Chief Robert Luna said at a news conference that when she returned to an afterschool program, adults noticed she wasn't feeling well.

She was hospitalized and had emergency surgery but died about six hours after the fight.

A coroner has not yet determined a cause of death.

Police are investigating and say no arrests are immediately planned.
