"We have received a complaint of drugging and robbery. The girl did not say anything about sexual abuse and hence a rape case was not registered," superintendent of police (North), Bosco George, told PTI.
The police are on the lookout for a group of Nigerians who allegedly committed the robbery, he said.
A group of six Nigerians allegedly spiked the girl's drink before robbing her on the night of December 31.
Police sources had on Sunday said the Dutch girl had complained of rape and a medical examination was being conducted on her.
"The medical examination was conducted as she was drugged," George said. However, sources said the tests were done to ascertain rape.
The Dutch girl, who is holidaying with her mother in the coastal state, had also failed to recognise the spot where the incident occurred.
"She was drugged and hence was not in a position to know the exact place," a police official said.
The incident occurred on New Year's Even when the entire state was on high alert with a ban on beach parties and a strong posse of policemen manning the beaches, especially isolated spots.
