Rajeevaru was questioned at an undisclosed location in the morning and later shifted to the SIT office in the afternoon, where his arrest was formally recorded, sources said.

According to officials, the arrest was made based on statements given by prime accused Unnikrishnan Potty and former Travancore Devaswom Board president Padmakumar.

The SIT found that Rajeevaru had close associations with Potty and had recommended the replating of the Dwarapalaka (guardian deity) plates and the Sreekovil (sanctum sanctorum) doorframe plates at the temple.

Later, when the Travancore Devaswom Board sought his permission for the replating, Rajeevaru had granted his approval, officials said.

SIT officials said Rajeevaru had been questioned earlier as part of the investigation.
