Security on the set of the Salman Khan-starrer 'Sultan' has been tightened after a snapshot of the star in a langot was leaked online recently.

The leaked pictures of a beefy and barebodied Sallu made several of his online fans go into a tizzy. But the star was not exactly amused. Buzz is that Sallu, who plays a wrestler, had apparently told the producers to refrain from taking any pictures of him in the langot.

The makers of the film are now on a hunt to track down the culprit. A strict vigil is being maintained to avoid any cell phones from making their way to the sets.
