A San Marcos drug lab that does business with several pro sports teams has surrendered its federal registration amid allegations it improperly filled prescriptions for the Chargers team doctor.
Dr. David Chao allegedly wrote 50 prescriptions to himself, and RSF Pharmaceuticals allegedly filled them; both actions are against the law.
On June 30, RSF voluntarily surrendered its DEA registration numbers to the DEA.
The company is no longer authorized to obtain, distribute, possess or manufacture controlled substances, according to a DEA spokeswoman.
The DEA said Friday that the investigation was still ongoing.
Earlier this week, search warrants connected to the case were unsealed that laid out evidence of the federal investigation accusing team physicians and pharmacies of writing and filling hundreds of illegal prescriptions for powerful drugs for Chargers, Padres and other professional and college athletes across the country.
The unsealed warrants targeted team doctors, alleging that three doctors for the Padres and two doctors for the Chargers wrote hundreds of so-called “suspicious and illegal” prescriptions.
Federal authorities began their investigation last May when former Chargers' safety Kevin Ellison was caught by police with more than 100 prescription pain pills.
Now, court documents reveal federal drug agents served ten search warrants under seal last month.
