Mumbai: Bombay High Court on Thursday issued a notice to CBI, seeking reply to a petition filed by extradited gangster Abu Salem, which expresses fear that he would be killed or implicate in a false case by the Indian authorities.

Salem sent a letter to the High Court to this effect, after the Portugal court recently revoked his extradition.

He had filed a similar application before the special TADA court which rejected it saying that there were no grounds or evidence to support his fear.

However, the division bench of Justices A M Khanwilkar and P D Kode on Thursday issued a notice to the CBI, seeking reply by December 7.

According to Salem's letter (written from Taloja prison near Mumbai), he has nine cases registered against him; and as the Portugal court has revoked his extradition, Indian investigating agencies may try either to implicate him in a false case, or orchestrate a fake encounter to kill him.

Salem was extradited from Portugal in 2006, and is one of the accused in the 1993 Mumbai serial blasts case.

The letter/petition seeks security, and a direction to the police and the CBI not to register fresh cases against him.
