Kolkata: A four-year-old boy was burnt to death when fire broke out in a small tile roofed house in South Kolkata, police said.

Kaustav Roy, who was alone in the Behala area house on Friday, was rushed to a hospital where doctors pronounced him dead.

Two fire engines managed to douse the flames after two hours.

The child's father -- a lorry driver -- and the mother, who works as a maid, had left the child at home.
