A 'Study of Child Abuse in Mizoram', prepared by the Social Welfare Department and Human Rights and Law Network (HLRN), revealed that 630 cases of child sexual abuse had been received during the period of 2003 to 2009.
Of these, 248 were received by the CID, 240 cases by district police stations, 124 by the Child Welfare Committee (CWC) and 18 cases by MHIP, Mizoram's apex women body.
Speaking at a preview workshop on the report, researcher Rohmingmawii, an assistant professor at Pachhunga University College, stated that almost 86.88 per cent of the victims were re-victimised by the same molesters.
She also pointed out that 12 cases of sexual abuse of boys were received during the period 2005 to 2009.
However, the actual number of such cases was 15 as three cases went unreported.
Most of those accused in sexual abuse belonged to the age group of six to twelve years.
''Child sexual abuse is also inflicted by older relatives of the victim like uncle, stepfathers and other people close to the family,'' a source in CWC indicated.
There could be more cases of abuse as many parents and victims dare not to approach the CWC for fear of stigmatisation of the victims, the sources said.
Most of those accused in child sexual abuse were aged between 19 to 35 and most of them were high-school dropouts.
The research also found a high percentage of children aged between 5 to 18 had access to pornography.
Of the 595 children interviewed, 55.78 per cent said that they had watched pornographic films.
