After a few months, Naved proposed marriage to her but the girl refused. However, Naved kept pursuing her when she stopped meeting him and discontinued her FB account.
"On April 30 evening, when the girl was returning home in Sanpada, Naved stopped her at Mora circle area. He was found accompanied by three of his friends and Sana, who was at the wheel of a BMW car," said Sawant.
Sana, Naved and his friends were already at her house when the victim reached home, where they had a heated argument before leaving.
"The girl's mother subsequently approached us on May 1 and lodged a complaint. The four boys were arrested on the same day while Sana is wanted in the case," Sawant said.
