Police is likely to file on June 28 a comprehensive chargesheet against Praveen Mahajan who has been arrested on the charge of killing his elder brother and BJP General Secretary Pramod Mahajan.
On June 28, Praveen would be produced before a magistrate for remand and the police is likely to file chargesheet, sources said.
On last occasion, the investigating officer had indicated that he was giving finishing touches to the chargesheet and was likely to file it on the next date.
Meanwhile, Pravin would file an appeal next week in a sessions court against the order of magistrate rejecting his plea for psychiatric tests and supervision of probe, his lawyer Nandkumar Rajurkar said.
"We shall file an appeal next week and I am going to meet Praveen in jail on Monday to discuss with him the details," Rajurkar said.
On June 14, a local court had rejected Praveen's plea to undergo psychiatric tests to ascertain his mental state when he had allegedly killed his elder brother. Twice earlier, the court had rejected a similar plea.
The magistrate noted that there were no grounds to show that he was mentally unstable and therefore rejected the petition.
The magistrate also rejected Praveen's plea that the court should supervise the investigation, as it was 'one-sided'. The court observed that the investigation was properly done and appeared to be fair and there was no reason to believe that 'pressure tactics' were followed by the investigating agency.
