The revelations have been made in the Central Bureau of Investigation (CBI) charge sheet filed against the accused for gang rape and murder in a Hathras court. The court has since taken cognisance of the charge sheet, the lawyer for the accused told reporters. The 19-page charge sheet, accessed by IANS, points out that the All India Institute of Medical Sciences' (AIIMS) Multi-Institutional Medical Board (MIMB) headed by Dr Adarsh Kumar, Professor of Forensic Medicine and Toxicology, has submitted its report to the agency. The MIMB report said that "...the possibility of sexual assault cannot be ruled out. The pattern of injury sustained during an incident of sexual violence may show considerable variations. This may range from complete absence of injuries (more frequently) to grievous injuries (very rare). In this case, since there was a delay in reporting or documentation or forensic examination for sexual assault, these factors could be responsible for the absence of significantly visible signs of genital injury."
