Bollywood star Aamir Khan, who was injured while doing a stunt scene for the film "Ghajini" here, flew back to Mumbai Friday for treatment, film industry sources said.

The mishap apparently occurred Wednesday when Khan had to lift and throw a bulky man weighing about 100 kilos, but the actor unfortunately pulled a hamstring muscle.

Directed by A.R. Murugadoss, "Ghajini" is a remake of a Tamil film by the same name. Actress Asin stars opposite Khan in the action-packed film whose theme revolves around revenge.

Actors Surya and Jyothika had acted in the Tamil original.
