Two sisters lodged a complaint against an NRI and two others for allegedly raping them at Nakodar area in the district, police said.

The victims, one of them 20-years-old and another three years younger to her, also contended in the complaint that the NRI's wife and a man had threatened them with dire consequences if police were informed of yesterday's sexual assault.

According to the complaint, the girls, along with their mother, had gone to NRI Jasbir Singh's house for preparing food. After their mother was sent to market, Jasbir, his driver Charanjit Singh and Gurcharan Singh raped them.

The complainants also alleged that NRI's wife Kamaljit Kaur and one Manga threatened them to conceal the crime.

Medical examinations were conducted to verify charge of rape, reports of which are yet to be available.

Though Charanjit and Gurcharan were arrested after registering a case against them, the NRI couple, who recently returned from England, and Mang are not taken into custody, police said.
