Story of Upakichakas and Bhima is mentioned in the Virata
Parva of the Mahabharata. The story takes place after the death of Kichaka, the
commander in chief of Virata. As per the Mahabharata there were 105 Upakichakas.
Kichaka who made sexual advances towards Draupadi was killed
by Bhima.
Next day morning the Upakichakas took the body of Kichaka to
the ghat to perform cremation. There they proclaimed that Draupadi was
responsible for the death of their brother.
They forcibly took her to the ghat and decided to burn her
on the same pyre of their brother.
Hearing the cries of Draupadi, Bhima rushed to her side and
killed all the Upakichakas.
