"Mahajan's remarks that he was offered bribe of Rs 100 crore to retain the tenders issued during the Congress-NCP regime are suspicious and people of the state should know the truth," NCP spokesman Nawab Malik said.
Mahajan caused a sensation when he said that he had stayed work orders worth Rs 1,100 crore which were hastily cleared ahead of elections by the Congress-led UPA government in the state.
Malik alleged that Mahajan was not revealing name of the contractor concerned because the latter has links with BJP.
"Mahajan should reveal the name of the contractor who offered the bribe. Did he (Mahajan) file a complaint with Anti-Corruption Bureau against the contractor who tried to lure a responsible person in government?" Malik asked.
A narco test should be conducted on the minister so that people will know the truth, Malik said.
