Kolkata: A Picnic Garden resident, a Class 11 student at an English-medium school who went to his tuition class 10 minutes away from home, ended up in the CCU of a govt hospital with poison in his stomach. The incident was reported on June 2, and the boy is yet to regain consciousness. The boy's parents said cops have collected samples from his stomach and sent them for forensic tests. Cops believe it was an attempt at culpable homicide, though they added it was too early to rule out a suicide bid.According to the complaint by the boy's father, the 16-year-old left home around 10.55 am and, on reaching his science tuition class that was being held at his friend's home on CN Roy Road around 11.05 am, he felt unwell. His friend's mother asked him what happened, to which he said he didn't have breakfast but he was in pain. They informed his mother, and asked him to take a bath. When they called a local doctor, he asked that the minor be shifted to a hospital. "The locals called an ambulance. At the hospital, doctors found the boy had been poisoned," the victim's father wrote in the FIR.Tiljala cops registered an FIR and said they are investigating all angles. "We are examining CCTV footage from the route the victim took. Our teams are also speaking with his classmates and friends to understand if there were any underlying issues," an officer said. "We have administered necessary treatment and are monitoring his condition. The toxicology report will help us understand the nature of the poison, if any," a doctor said.
