SHERMAN, Texas (KXII) -- A local pain management doctor was arrested Tuesday, two months after his offices were raided by federal agents.
Diamond was taken into custody while one patient said he was waiting at the Sherman office, in need of his medication.
"This doctor is one of the best pain management doctors in this area, the man does not deserve what is going on," Brian Lawrence said.
Brian Lawrence has gone to Dr. Howard Gregg Diamond for his chronic pain the last eight years.
Tuesday, he came in for his appointment, but was told the office is closing.
"What I was told today, Dr. Diamond won't be back here, they'll be a new doctor next Tuesday. I don't want to see a new doctor, I want to see the doctor I've been seeing," Lawrence said.
This also means Lawrence won't have his medication for another week.
"He's probably not gonna be able to get out of bed and spend time with me or our kids or anybody," Lawrence's wife Kathleen Lawrence said.
Back in May, the Drug Enforcement Administration and FBI agents raided the Diamondback Pain and Wellness centers in Sherman and Paris. At the time, the FBI said it was for failing to maintain sufficient medical records.
According to the Texas Medical Board, Dr. Diamond had to pay $500 and complete extra training for the same problem in 2015.
But this time around, the FBI isn't yet saying why he's been arrested.
"I do but I don't know if it's public record yet. As soon as I get confirmation from that, I'll send a news release that will go out but I haven't received anything yet," FBI Eastern District Spokesperson Davilyn Walston said.
Dr. Diamond has posted on social media about the problems he had with local pharmacies refusing to fill prescriptions and stated on Facebook last month, "I'm doing my best to meet any need and to manage the government."
As for Lawrence, he said he just hopes he gets to see his doctor again.
"That man is a wonderful man, that they are trying to bring down because they are not investigating the right way," Lawrence said.
