The arrest of a man who allegedly sexually assaulted a six-year-old girl in his wife’s care has revealed a more heinous crime where he allegedly raped and murdered a four-year-old child he had abducted last year. Somanna (50), the husband of Bailamma, an anganwadi worker in Yelahanka, was arrested after the parents of a child in Hunasamaranahalli anganawadi found injuries on her body when she returned home on Thursday. When the child conveyed that Somanna had molested her in the kitchen when Bailamma was not around, they went to the Yelahanka police. During interrogation, he reportedly confessed to have kidnapped, raped and murdered a four-year-old girl whose body he dumped in Kodigehalli lake near Chikkajala.
