Prosecutors in San Bernardino County, California, have filed felony assault charges against three sheriff's deputies involved in the televised beating of a suspect after he tried to escape on horseback.

District Attorney Mike Ramos said Tuesday that Nicholas Downey, Michael Phelps and Charles Foster each face a charge of assault by a public officer.

Seven other deputies placed on administrative leave were not charged.

The county Sheriff's Department submitted its investigation to the district attorney last month.

A KNBC-TV helicopter news crew followed the April chase as Frances Jared Pusok fled deputies on a stolen horse. It then televised deputies repeatedly punching and kicking Pusok as he lay on the ground.

The county reached a $650,000 settlement with Pusok. He has been charged with 14 felony and misdemeanor counts.
