Federal agents raided an office of a well-known radiology company in Suffolk Tuesday.

FBI agents collected dozens of boxes of medical records from Zwanger-Pesiri Radiology in Lindenhurst as part of an investigation into health care fraud, officials told News 12.

Sources at Newsday say the raid stems from an investigation into allegations that the company engaged in a multimillion-dollar fraud by overbilling the federal Medicare program for services, including X-rays, MRIs and CT scans.

Officials did not comment about how long the radiology giant was being investigated or how many people may have been affected.

They say a second location in Lindenhurst at Sunrise Plaza of Wellwood Avenue was also raided Tuesday. Agents on the scene said the small, seemingly vacant office space was involved in the investigation.
