Kozhikode City Police Commissioner A V George told PTI that some activists of the 'Kiss of Love' and 'Hanuman Sena' have been taken into custody.
Some activists of 'Kiss of Love' had just reached the bus-stand for the protest when they were whisked away.
"We are looking at the situation. So far no ban has been imposed in the area. If there is a law and order issue, we will think about it," he said.
A Facebook collective of "Free Thinkers" led by Rahul had been arrested and removed by police when they tried to stage the Kiss protest on November 2 at Kochi.
