Police said the woman, known as Seema, had been in a serious relationship with Mehboob, a married man with four children, over the past two years.
He had allegedly promised to leave his wife for her but went back on his word.
It was reported that Mehboob had tried to stab her a few days earlier.
Police said Mehboob was tricked into a final meeting, where Seema, her younger brother and cousin were waiting.
While he was talking to Seema, he was hit on the head by her younger brother and knocked unconscious.
He was later strangled and burnt and his body was dumped in the nearby forest.
