Congress leader Shashi Tharoor on Monday said whatever his party colleague Vijay Wadettiwar said about the death of then Maharashtra ATS chief Hemant Karkare during the 26/11 terror attack must be investigated, reported news agency PTI.

Wadettiwar, the leader of opposition in the state assembly, had recently claimed Karkare, who was the Maharashtra Anti Terrorism Squad chief during the 26/11 terror attack, wasn't killed by Kasab's bullet but by one fired by a policeman affiliated to RSS.
