A court in India has cleared Bollywood star Salman Khan of keeping firearms illegally.

A court in Jodhpur city said the prosecution was not able to prove that Khan used firearms to kill endangered black bucks two decades ago.

The actor has already been acquitted in two cases of poaching, while a third case is still being heard in Jodhpur, in the northern state of Rajasthan.

Khan, 51, is one of Bollywood's biggest stars, appearing in more than 80 films.

The actor was charged with killing two black bucks, a protected antelope species, and keeping firearms illegally during a trip to a forest in 1998.

He had pleaded not guilty in all these cases.

The original case against him was filed by the local Bishnoi community, who revere and worship the black bucks.

In 2006, a trial court convicted the actor in two cases of poaching and sentenced him to five years in prison.

The Rajasthan high court suspended the sentence the following year, and eventually acquitted him last year.

The state government has appealed against that order in the Supreme Court.

In 2015, Khan was also acquitted after being charged with running over and killing a homeless man in a driving accident in Mumbai. The Maharashtra state government has challenged the order in the Supreme Court.
