According to the police, the victim - who works as a caretaker at a house in the area - was sleeping alone when the accused, Sanjay Kumar, barged into her room. The accused is the victim's neighbour.
In November 2010, a 30-year-old call centre employee from Mizoram was allegedly abducted by five men, when she alighted at Dhaula Kuan. The woman was raped in a pick-up truck and then dumped in Mangolpuri. The police have arrested all five accused.
In February this year, a drunkard in the Dhaula Kuan area allegedly molested a 25-year-old woman who works at the Indira Gandhi International Airport in the wee hours.
Meanwhile, the police said that in the present case, the woman had been living with her elder sister for the last few years. "The accused accosted the woman and then tried to be friends with her. When she refused, he wanted to take revenge," said a police officer on condition of anonymity.
The police said that on the night of November 19, the accused sneaked into the house of the victim and allegedly first threatened her and then raped her. On hearing the commotion, the victim's elder sister came out of her room. After that, the accused tried to flee the spot.
The police said they have nabbed the accused.
In a similar incident, a jilted lover has been found harassing a woman in the Satya Niketan area. The accused Rahul, 22, went to the office of the 20-year-old woman who works as a receptionist and threatened her.
"On February 17, the accused went to her office and tried to forcibly take her along with him," said a police officer. "A police constable nearby saw the whole incident and came to the rescue of the woman."
