The Supreme Court on Tuesday ordered a Central Bureau of Investigation probe into the appointment of 3000 teachers by the Haryana government after a petition alleged the actual selected list of the teachers was given a go by and candidates selected by Haryana Chief Minister Om Prakash Chautala were 'substituted'.

A bench comprising R C Lahoti and Justice Ashok Bhan asked the CBI to complete the probe into the appointment of teachers made in 2000 within six months and register a case if any offence is disclosed.

The order was passed by the bench on a petition filed by IAS officer Sanjeev Kumar, former education director of the state, alleging that Chautala had threatened him with 'dire consequences' if he did not 'substitute' the actual selected list of candidates for appointment as teachers with the one supplied by the political leadership.

Keeping in view the allegations made against Kumar by the Haryana government, the court also asked CBI to probe the same.
