Surendran along with three others arrived at Nilackal around 7 pm, just after a hurriedly called dawn-to-dusk hartal to protest Hindu Aikyavedi leader K P Sasikala's midnight arrest had ended. They were about to board a bus to the Pamba base camp and further to the Sannidhanam inside the temple complex when a police team blocked their way and said they should come back on Sunday morning for the darshan .
Surendran and the three men had proper pre-booked passes and were also willing to submit themselves to frisking and other security checks. But the police informed him that due to the tense situation at Sabarimala, he would have to go back or they would have to arrest him .
