Amar Kumar Behera had allegedly committed the crime yesterday, when the girl and the woman were waiting for a bus at a passenger shed in Rajnagar area, police said.
When the victims raised an alarm, an angry crowd chased the accused and apprehended him. Behera was allegedly in an inebriated state at that time, they said.
"It is very unfortunate incident. This sort of act and behaviour is bound to lower the image of police. The accused has already been placed under suspension," Kendrapara Superintendent of Police Dayanidhi Gochayat Behera said.
Behera was arrested and a case under under sections 323 (voluntarily causing hurt), 341 (punishment for wrongful restraint), 354 (assault or criminal force to woman with intent to outrage her modesty) of IPC and section 8 of Protection of Children from Sexual Offences Act (POCSO) was registered against him.
He was later produced in a local court which rejected his bail plea and was sent in jail.
