PADUCAH — Out of the office and into the jail: a local doctor turns himself in on drug trafficking charges.

He stands accused of providing powerful pills in exchange for personal favors.

Since first reporting the charges Friday afternoon, we now know more about how Paducah doctor Troy Nelson was caught and why he turned himself in.

We asked police about the nature of the "personal favors" and they said they're not comfortable with going into details about what the seven people Kentucky State Police say did favors in exchange for pills.

We're talking about drugs like oxycodone, hydrocodone, xanax and others.

KSP say it was an undercover detective who traced multiple narcotics to Nelson.

Nelson and his attorney kept silent while walking into the McCracken County sheriff's office. The doctor turned himself in.

Minutes later, deputies cuffed Nelson took him to jail.

He's accused of illegally dispensing meds such as oxycodone, hydrocodone, xanax, tramadol and others.

But Nelson wasn't behind bars for long. Less than 20 minutes later, he posted bond.

His attorney Mark Bryant told us after the state board of medical licensure found out about the accusations. Bryant said the doctor temporarily handed over his license to prescribe narcotics but the board allowed him to keep practicing medicine.

Bryant said while his client did make some mistakes, he's not a criminal.

"I am denying he is a drug trafficker," Bryant said. "I think those charges are absolutely ridiculous. If that had been the case, the board would've never allowed him to practice medicine."

Bryant said he wishes Nelson could be kept out of court and the matter handled by the state licensure board.

"This is a man who's never been in trouble his whole life but the state police decided they wanted to take him in in handcuffs," Bryant said.

But the grand jury indicted him on eleven counts, seven of them are felonies.

The indictment mentions seven different people who got meds in exchange for favors. During a period ranging from October of 2010 to July 2011.

He's not writing controlled substance prescriptions for now. However, his office will remain open and he will keep seeing his patients.

Nelson is due back in court at the end of the month.

The investigation is ongoing by the Kentucky State Police and the U.S. Drug Enforcement Administation.
