The BJP MLA had earlier stirred controversy by saying that he would oppose riot refugees from voting in his constituency Kairana as they were living “illegally” on government land.
Singh was among the 16 politicians and community leaders who were accused of inciting violence through inflammatory speeches in Muzaffarnagar and had been briefly under arrest.
More than 60 persons were killed and over 40,000 displaced in riots that had taken place in Muzaffarnagar and adjoining areas in September last year.
The elections in UP are scheduled to be held in six phases. The Kairana Lok Sabha constituency goes to poll on April 10.
