SANTA ANA – A Long Beach man has been arrested for allegedly being part of a ring that stole about 100,000 doses of the prescription pain drug OxyContin from about 30 pharmacies.

Authorities say 26-year-old Brian Allen Richard was arrested Wednesday and was being held without bail at the Orange County Jail.

Orange County sheriff's spokesman Jim Amormino says authorities were led to Richard after DNA evidence was gathered from blood left at a Walgreens in Mission Viejo where one of the burglaries occurred.

The pharmacy thefts began in June and continued into September. They included six in Orange County and others in Fontana, Long Beach, Palm Springs and San Bernardino.
