PATHANAMTHITTA: Dress code has been made mandatory for policemen deployed in Sabarimala. The policemen have been instructed to wear khaki uniform, cap, belt, shoes, shield and lathi. Policemen deployed at the eighteen steps and Sopanam have been exempted from it. Such restrictions have been given in order to face the untoward incidents that happen and for a smooth pilgrimage season. Meantime, a large flow of devotees will be witnessed when the sanctum sanctum opens this evening. Devotees from other states have reached Sabarimala but they will be allowed to enter Pampa only from this evening. The law enforcement has marshalled over 15,000 officers to uphold the peace in Sabarimala over the 63-day pilgrim period.
