BJP general secretary K Surendran was allegedly taken into preventive custody Saturday night and removed by police from Nilackal, the base camp, as he tried to leave for the Lord Ayyappa shrine at Sabarimala.
Surendran, who was carrying the "Irrumudikettu" (bundle containing offerings for the Lord), was told by a police team led by Yatish Chandra, Superintendent of Police, not to proceed to the shrine as it would create law and order problems.
Surendran told the police he had come as a "Ayyappa Bhaktha" (devotee) and should be allowed to pray at the temple.
Chanting "Swamiyae Ayyappa", Surendran and others with him jostled with police and tried to move forward saying there was no question of going back.
Three of his supporters were also with Surendran when he tried to leave for the shrine.
They were removed by police and taken in a jeep.
Surendran later told PTI that he was being taken to the Chittar police station and said he did not know if he was being arrested or detained.
He also said he had taken receipt for performing the 'Neyyabhishekam' (ghee offering) ritual and 'Ganapathy Homam.'
