Gurugram, June 22 -- Police have opened a murder investigation on Sunday after a three-year-old boy was found with his throat slit at his residence in Faridabad's Shiv Durga Vihar. The parents of the child, who were allegedly not at home at the time of the incident, were also detained for questioning, said officials. According to police, the boy's aunt, who was the only one present in the three-bedroom residence, discovered the boy's body in bed around 10.30am. She was allegedly in another room when the incident took place. The landlord, who lives in another portion of the house, called the police after hearing their cries and reaching the spot. "The child was found dead on a bed with severe injuries to the throat. The forensic team has collected evidence from the scene and all aspects are being probed," said Yashpal Yadav, Faridabad Police spokesperson. According to police, based on the condition of the body, the incident is suspected to have taken place around 9am when no one was present in the room. Police have detained the child's parents for questioning and are also recording statements of the aunt and other family members to reconstruct the sequence of events. Investigators suspect the child was attacked with a sharp-edged weapon, though the exact nature of the object used has yet to be established. Police said they are examining all possible angles, including family disputes and the movements of those present in the house at the time of the incident. Officials said the family had recently shifted to the locality from Uttar Pradesh. According to neighbours and the landlord, the victim was the couple's only child.
