BLOOMFIELD HILLS, Mich. -

A Bloomfield Hills dentist will pay $125,000 to settle claims from federal investigators that he wrote illegal drug prescriptions.

In exchange for the deal, federal authorizes said they won’t file a lawsuit against Dr. Marc R. Kamp.

The 54-year-old was accused of writing prescriptions between 2009 and 2013 for controlled substances -- such as hydrocodone -- that were not intended for a legitimate medical purpose.

Investigators said as least two Birmingham Public Schools bus drivers were among the people Kamp wrote the prescriptions for.

Kamp also settled government claims that he falsified applications for his DEA registration in both 2009 and 2012, by failing to indicate that his state dental license had in the past been suspended.

In the 2009 application, he failed to report that his dental license had been suspended for six days in August, 2009, a result of a felony ethnic intimidation conviction.

Again in 2012, Kamp failed to report that his license had again been suspended – for four days in January, 2011 -- for practicing dentistry during his August 2009 suspension.

Earlier this year, while facing administrative action by the DEA to revoke his controlled substances registration, Kamp voluntarily surrendered that registration.
