VHP had asked its activists on Friday to perform rituals on the bank of Saryu to mark the conclusion of their yatra, which was banned by the state government.
On the last day of the yatra, 52 people were arrested while trying to move towards the culmination point of the parikrama in Basti.
"52 people trying to move towards Makhauda village in Basti , the culmination point of the yatra, were arrested," IG (Crime) Ashish Gupta told reporters here.
"During our security flag march, we had warned of dire consequences to anyone who would try to violate the law and order, peace and communal harmony," Faizabad DM Vipin Kumar Dwivedi said.
The IG said there was no report of any untoward incident from anywhere, including Ayodhya, today with security personnel maintaining a constant vigil.
VHP had proposed to take out 84-Kosi Parikrama yatra from August 25 to September 13. The yatra was banned by the UP government.
