The Madurai district crime branch police officers conducted simultaneous raids in the residences of P.R. Palanichamy and some of his associates in the city and suburbs on Thursday.

According to sources, the teams had carried out the checks after a recent interrogation with the granite baron’s son, Suresh Kumar, and eight others in connection with the alleged multi-crore scam in the granite quarrying business. Though the officers were tight-lipped about the outcome of the search, a senior officer said that eight teams comprising Inspectors, Sub-Inspectors of Police and others led by DSP Thangavel carried out the operation for over three hours. Further investigation is on.
