Names of suspended employees are Macchindra Thorat (materials manager), Prakash Dighe (pharmacist) and Dilip Adicchya alias Sharma (store manager), SSST Executive Officer Rajendra Jadhav said.
After complaints were received by the SSST, documents and medicine stocks were verified, he said.
"We found a difference at the primary stage. Discrepancies were found in the tendering process," he said.
Jadhav said that though the Shrirampur-based spirit supplier is supposed to have supplied the spirit using company vehicles, it was found that the SSST's vehicles were utilised to transport the spirit to the hospital.
Meanwhile, Right To Information (RTI) activist Sandeep Kulkarni, who studied documents related to the scam, demanded a thorough inquiry, failing which, he would knock at the doors of the high court.
