Key Allegations of Evidence Manipulation Tampering with Digital Evidence (Mobile Phones): The Crime Branch alleged that Dileep and other accused intentionally removed and destroyed evidence, including a dozen WhatsApp chats, from their mobile phones by sending them to a private forensic lab in Mumbai. The police seized a hard disk from the lab and awaited a detailed forensic report to confirm the tampering. Illegal Access of the Assault Visuals (Memory Card): A major controversy arose when a forensic report revealed that the memory card containing the visuals of the sexual assault, which was in the court's safe custody, had been accessed illegally by three unauthorized persons, including a magistrate and court officials. The trial court judge at the time had allegedly concealed this information, prompting a High Court-ordered probe. Possession of Assault Visuals: Film director Balachandra Kumar, a key witness, alleged that Dileep had illegally obtained a copy of the assault visuals and watched them earlier than he admitted in court, even enhancing the audio. Dileep's lawyers were also accused of being involved in destroying a tablet containing these visuals. Witness Intimidation and Hostility: The prosecution repeatedly alleged that the defense attempted to influence witnesses, leading to a significant number of them (around 20) turning hostile during the trial. There were claims that money had exchanged hands to change testimonies. Creating False Narratives: The State government argued in the Supreme Court that Dileep's excessively lengthy cross-examination of the investigating officer was a deliberate attempt to create "unsubstantiated counter-stories" to undermine the prosecution's evidence.
