The four additional people are related to the victim who died after the fight.
Four more people have been arrested in connection with a deadly riot in Circleville last week.
Daniel Harris, Angel Haines are charged with aggravated riot. They are being held on a $500,000 bond and will appear in court Tuesday. Shyia Harvey and Preston Harvey, both juveniles, have been charged with riot. All four are related to the victim, Brittany Jeffers, who died after the fight.
Four other people had already been charged in the case.
"All the active participants have been charged. Unfortunately, Brittany did die in this incident and we're trying to determine what caused that," Circleville Police Chief Harold Gray said.
He's hoping to have a preliminary report from the medical examiner's office soon, but the final report won't be made until four to six weeks. More arrests are possible, but Gray said they won't know until they see the final coroner's report.
He's heard rumors that there is video of the fight, but so far none has surfaced. He says they would be very interested in seeing it if anyone has it.
Gray says Jeffers' family and others involved in the fight had been feuding for a while. The situation apparently came to blows when Jeffers' mother called in a tip about seeing someone breaking in to a neighbor's home.
"The cause was not the phone call. The cause happened a long time ago," Gray said.
Gray is hoping to get the case to the next Pickaway County Grand Jury.
Funeral services for Jeffers are planned for Thursday.
