A young Bollywood star, Meenakshi Thapar, has allegedly been kidnapped and beheaded by two fellow actors.

The 26-year-old actress met Amit Jaiswal and his lover Preeti Surin on the set of her latest film, Heroine, the UK's Daily Telegraph reports.

It was there that Jaiswal and Surin heard of her family's wealth, and allegedly hatched a plot to kidnap her.

The duo are said to have invited Thapar to a small town on the Nepalese border, where they took her hostage and demanded 1.5 million Rupees ($A27,800) from her parents, and threatened to force her into pornography if they were not paid.

Although Thapar's parents are thought to have transferred some money to their daughter's captors, the young star was killed soon after.

A detective working on the case told The Telegraph some of the harrowing details:

"She was strangulated in a hotel and her body was hacked into pieces and thrown in a water tank. They threw her head from a moving bus while travelling back to Mumbai."

The case is ongoing.
