Terming the act as "intolerable", Gaikhangam, who holds the home portfolio, told the Assembly that serious action would be taken against them.
"The four IRB personnel, including three havildars and one rifleman, have been suspended and are now in police custody," he said.
Official reports from the interior district said the girl and her boyfriend were roaming around picturesque Khuga dam complex yesterday when they were caught by the four IRB personnel.
Instead the four men assaulted the two and forced them to take part in an "obscene act" and the pictures were then uploaded by the four personnel on the Internet, the reports said.
The incident enraged the local inhabitants who thronged the police station to hand over the four to the public, the reports said.
Three persons were injured when the police opened fire and burst tear gas shells to disperse the mob, the reports said.
The pictures have been removed from the internet, the reports said.
