"None of our fancy government summits in Delhi will undo the damage done to relations with countries in Africa by incidents like #Bangalore," he wrote on Twitter.
The National Conference working president was reacting to the incident in Bengaluru where a Tanzanian woman student was allegedly beaten up and stripped by a mob in a case of "mistaken identity" after a woman was mowed down by a car.
The 21-year-old Tanzanian, who is doing her Bachelor of Business Management course, was dragged out of the car in which she was seated along with her three friends.
