A businessman named Unnikrishnan Potty, who sponsored the gold electroplating of the Dwarapalaka (guardian deity) idols at Sabarimala temple, was questioned for the second consecutive day on Sunday. He was questioned by the Travancore Devaswom Board (TDB) Vigilance team in the case of missing gold from the gold-cladded copper panels donated by Vijay Mallya to Sabarimala temple in 1998.
