A doctor who was suspended from practicing after he was found curled in the fetal position on the floor of his Bowie office is being investigated by federal authorities for allegedly prescribing “excessive amounts of controlled substances,” court documents said.

Dr. Rajan Sood was suspended by the Maryland medical board Feb. 13 after officials concluded he was addicted to a variety of narcotics, according to the board’s February newsletter. The board also found Sood, a general practitioner, was writing multiple prescriptions for family members and office staff.
