EDINBURG – Federal authorities have shut down a medical office for the day. Patients with appointments are being turned away.

An FBI spokesperson is providing very little information about the presence of agents inside the Center for Arthritis and Osteoporosis in Edinburg.

CHANNEL 5 NEWS arrived to the scene shortly after 9:00 a.m. An Edinburg police unit was on scene as well as a number of unmarked vehicles and a moving truck.

Agents were seen escorting what appeared to be employees one by one out of the building.

Multiple agents have made their way in and out of the building.

Agents opened the back of the moving truck and brought boxes, files, coolers and tables in to the building.

According to FBI Special Agent Michelle Lee, the agents are conducting law enforcement activity. Lee said the FBI is working alongside several agencies at Cornerstone Boulevard.

Many patients were confused and frustrating after being turned away for treatment.

“Who knows what could’ve happened,” Barbara Barios said. “All they told us is that today we couldn’t be seen.”

Barios shuttles various patients two times a week to Cornerstone Boulevard. She said all the patients live in Starr County. One patient was unable to receive her weekly treatment.

According to an officer on scene, the center will reopen on Friday.
