Chennai: In a bizarre incident that has come to light from Tamil Nadu, a man stabbed three people after they tried to thwart his suicide attempt. Police have identified the man as 30-year-old K Karthik Nivas, a resident of Tiruvalluvar Nagar in Chennai's Alandur area. An officer familiar with the case said that the incident took place on Saturday night.

Going by inputs, Karthik lives with his parents. On the night of the incident, he forced his parents to step out of the house and locked himself inside. Terrified that he would kill himself, the parents called for help. Their cries were heard by 55-year-old Manivannan and his 53-year-old wife Leelavathi along with 45-year-old Mary Valarmathi. While the couple lives in the apartment above the accused, Mary lives next door.

The three rushed to the aid of Karthik's parents and kept knocking on the door for several minutes but to no avail. Suddenly, Karthik opened the door and charged at his three neighbours with a pair of scissors. According to a report, the couple escaped with minor injuries but the accused stabbed Mary in the neck. She was rushed to a private hospital where she is being treated in the ICU.

Meanwhile, St Thomas Mount police have registered a case against Karthik. His parents said that he is mentally challenged. Karthik worked in a car manufacturing unit until recently and had been out of a job for almost seven months. More details are awaited as this is a developing story and a police investigation into the matter is underway.

In August of this year, the video of a boy saving the life of a woman after she attempted to take her own life had gone viral on social media. In the video, a private university student can be seen running to the woman as she sits on a ledge and threatens to jump. The boy manages to get a hold of her arm just as she jumps. Soon after, two other people join the boy in pulling up the woman and save her life. The video was reportedly shot in Uttar Pradesh's Noida.

Similarly, an alert constable with the Railway Police Force (RPF) saved the life of a woman in August after she attempted suicide at the Vidisha railway station in Madhya Pradesh. Footage retrieved from CCTV cameras installed at the station shows the woman walking towards a train. Two RPF jawans spot her and run to her rescue.
