Sleuths of National Investigation Agency (NIA) carried out a search at the house of the four accused in 2016 murder of Hindu Munnani leader C Sasikumar in Coimbatore.
Taking up the investigation into the murder of Sasikumar, the NIA has recently sought custodial interrogation of two suspects who were arrested in the connection with the murder.
NIA officials interrogated two accused in the murder case at the NIA temporary office at Race Course on Thursday and Friday.
The agency had sent summons to S Saddam Hussain of Saibaba Colony and Syed Abudhakir of KK Pudur in Saibaba Colony to appear before it.
The duo had obtained conditional bails a few months ago. Though NIA filed a petition before the special court for NIA cases in Poonamalle seeking their custody, the court dismissed the petition on Friday.
The NIA officials, who took over the probe from the CB-CID of Tamil Nadu police last month, searched the houses of Saddam Hussain, Abu Thahir, Subair and Muhammed Mubarak.
