A 36-year-old Finnish national was allegedly raped by an unidentified man in the satellite city of Navi Mumbai, the police said on Wednesday.

The victim, who works for a Finnish machine tool company and is in India on a professional visit, was found with some bruises by a police patrol party sitting outside a petrol pump in the CBD Belapur node in the wee hours of Tuesday.

"She refused medical assistance from us and went to a private hospital in Mumbai for treatment today where she told the doctors that she was assaulted and raped following which a complaint of rape was registered today," Commissioner of Police Navi Mumbai Ramrao Wagh told PTI.

According to the victim she had food and liquor at Hotel Indulge in Belapur late on Monday night. She went out of the hotel alone and started searching for an autorickshaw to return home nearby, but could not get a rickshaw and had to take a lift from a private vehicle, Wagh said.

The driver took her to the nearby Parsik Hill and dragged her out of the vehicle. He then assaulted and raped her, Wagh said, adding, the victim resides in Navi Mumbai.

The medical examination reports of the victim are awaited and the police is also searching for any eyewitness in the matter, Wagh said.

"The same woman was found in an inebriated state roaming around alone in the late hours in CBD Belapur two months ago," Wagh added.
