The pilgrims, who were picked up from different places including Nadapandhal, Mallikapuram and near the 18 holy steps, were carrying the 'irumudi' offerings to be made at the Ayyappa shrine, when they were arrested, police said.
All the pilgrims hail from Kerala.
The devotees are required to follow 41-day fast prior to the pilgrimage and abstain from consuming non-vegetarian food, alocohol and tobacco.
Meanwhile, a 55-year-old Sabarimala pilgrim from Andhra Pradesh died of a cardiac arrest at a hospital here.
