"We do know that Headley had visited India a number of times. That is being investigated," he told reporters here when asked about media reports which said that the US citizen had visited the country.
"He has been in Mumbai and some other places," the Home Secretary said to a question about the places Headley had visited in India.
49-year-old Headley was arrested last month at Chicago's O'Hare International Airport as he prepared to board a flight to Philadelphia, intending to travel to Pakistan. FBI also arrested Tahawwur Hussain Rana, 48, a Canadian citizen of Pakistani origin, in the case.
Rana was arrested for planning attacks on National Defence College in Delhi and some other installations in the country.
