An official press release said Mr. Chidambaram and some members of his family (wife, son, daughter - in - law and grand-daughter) were dining out with some friends when the photographer of a newspaper approached them repeatedly and asked for permission to take photographs. Each time, his request was turned down as the family was on a private visit.
Police sources said there was a scuffle when the photographer of The Times of India attempted to take pictures as the family came out of the restaurant. An attempt was made to snatch his camera and in the melee the Minister tripped and fell.[Link]
