Bobby Joshi said that he received a call warning him of serious consequences for speaking on the matter.
"You are speaking too much. We will see you. Following the threat call, I complained to the IG (Police)," Joshi told ANI.
"I am not scared of any threat. There is another lady, who also saw everything that happened that day. During the Jat agitation, I saw some rogue elements near Sukdev Dhaba creating ruckus and misbehaving with ladies," he added.
After rejecting the reports of sexual assaults in Murthal, the Manohar Lal Khattar-led government had earlier this week told the Punjab and Haryana high court that a section of gang-rape has been added in the FIR registered on the basis of a complaint filed by Bobby Joshi on March 30 alleging gang-rapes during the Jat quota violence.
The Punjab and Haryana high court had taken suo motu notice of media reports that some women, who were commuting on the Delhi-Ambala Highway (NH-1), were stripped and raped by rioters during the Jat agitation over reservation in government jobs.
The Haryana government had initially told the court that no incidents of rape or molestation had taken place.
