Mumbai, Nov 16 : The National Investigation Agency (NIA) on Monday asked Rahul Bhatt, son of film director Mahesh Bhatt not to leave Mumbai, as a restrictive order.

The NIA has also told Rahul that if he wants to leave the city, he should inform them of his travel plans.

The NIA began quizzing Rahul after it was discovered that he had met alleged Lashkar operative David Coleman Headley, who was arrested by the Federal Bureau of Investigation (FBI) for plotting a major terror attack in India.

Headley was also in Mumbai for five days prior to the 26/11 attacks.

The NIA suspects that Headley and Pakistan-based Lashkar operatives may have seen the former''''s familiarity with Rahul as important for their terror plans in India.

According to investigating agencies, Headley had met Rahul during his visit to Mumbai. His name also cropped up in several email conversations with co-accused Tahawwur Rana.

According to the Mumbai Police, Rahul came into contact with Headley through Vilas who worked at the Moksha gym in the Breach Candy area of south Mumbai. (ANI)
