Plotter Abhimanyu and his siblings, Anu, Archana, Anshu, Anurag

KAPURTHALA: A 21-year-old youth gave burgers laced with insecticide to four of his six younger siblings and a cousin before consuming the same at Lakshmi Nagar in Kapurthala on Tuesday night.

All the five siblings, including three girls, died and the cousin is admitted to a hospital. The youngest sister and a brother escaped as they were sleeping when the incident occurred.

According to police, Abhimanyu Kumar had left a suicide note in which he stated that he was unhappy that his parents were facing a lot of trouble to take care of the entire family.

Abhimanyu and his father Ram Kishore , originally from Bihar, were running roadside hair-cutting vends at different locations in the town. His mother Rita Rani said he came home around 10pm and brought burgers with him.

He gave it to his three sisters - Anu Kumari (17), Anshu Kumari (15) and Archana (7) - and brother Anurag (10) and cousin Hari Nanda (21). Within minutes they started vomiting and their condition deteriorated.
