ASI Narinder Singh, along with a constable, intercepted seven youths, who were on their way to attend a religious function at a shrine in Patiala on Sunday, they said.
Amardeep Singh, one of the victims, alleged that the ASI was in an inebriated state and started misbehaving with them.
In his complaint, Amardeep Singh claimed that the ASI physically tortured them and then took him to a secluded place and poured liquor into his mouth.
Describing the allegations as "serious in nature", SSP Mandeep Singh Sidhu suspended ASI Narinder Singh and ordered a probe into the matter.
"The police have registered an FIR against the ASI for torturing the youths and a departmental inquiry has been started against the SHO," Sidhu said.
A Medico Legal Report (MLR) of Amardeep Singh mentioned injuries throughout his body, the officials said.
The medical report mentioned injuries on his head, neck, chest, legs and also on private parts of Amardeep Singh, they said.
According to the report, he was also given an injection, forcibly, of an unknown drug, the officials said.
Along with this, the report of another victim Nitin Mehra's MLR has also been provided. He had similar injuries on his head, neck, chest, legs and other parts, they said.
According to the victims, they were issued challans because there were three people on one bike and the pillion rider was not wearing a helmet.
Amardeep Singh claimed that they were let-off on Monday morning after "they made us sign a paper".
Meanwhile, the ASI has denied all the allegations and said the youths misbehaved with him.
AAP MLA Sukhpal Singh Khaira has demanded dismissal of the police official from the service and registration of case under Section 307 (attempt to murder) and 295 A (hurting religious sentiments) of the IPC against all the officials involved in the incident.
"We give 48 hours of ultimatum to the government to act on our demand otherwise we will gherao Sanour police station," he said.
