NEW DELHI: The British national who was arrested for sexually assaulting three blind teenagers in south Delhi is suspected to have targeted a dozen more children, including some from the same institution. Interrogations have revealed that the man had lured them on the pretext of having a quiz contests. The children would be rewarded with money or gifts to keep them from registering a complaint with the management.Police sources say that the man, Murray Denis Ward, has been associated with some other NGOs for philanthropic work. The man claimed that he has been doing it for the past few years and his target age group was 8-12. Ward will be produced before a court on Thursday.During interrogation, Ward had refused to accept that his activities were criminal and had tried to justify the act. Police say that even while travelling to Kota recently he had visited some NGOs where cops suspect that he might have targetted some children.The online chat groups in which he shared videos and photos of children being sexually assaulted were traced to different countries. He has been taken on a two-day police remand to find out if he clicked some of the sexually explicit images found on his phone with other paedophiles.A team from the Delhi Legal Services Authority has also been roped in to help cops counsel the victims whose photographs were found in Ward’s phone. Sources say that he had bought the phone recently and his previous chat history needs to be verified from his backup folders.Cops suspect that he might also be a part of some secret online group of paedophiles who might be involved in sharing explicit photographs among each other. Efforts are being made to identify the members of the other group as well.Sources say that when the accused was caught on Sunday, he tried to defend himself by refusing to accept that sexually assaulting a child was a crime. He later tried to convince the cops that he was being the falsely framed by the blind school and they have been using doctored images to implicate him. In order to verify the allegation, cops have sent the mobile phone of the employee from the blind school who had caught the man red handed for a forensic analysis.
