Four members of a family, including a one-year-old girl, sustained injuries when a cooking gas cylinder exploded inside a house in the Gazi Mandai area of Lucknow city on Sunday afternoon.
The two-storey house collapsed due to the impact of the blast that is likely to have occurred due to a leakage in the gas cylinder, the police said.
The victims, identified as Jagdish Kashyap (65), his daughter-in-law Pinky Kashyap (38), granddaughter Vidisha Kashyap (1), and nephew Raj Kumar (52), are currently undergoing treatment at a hospital. Their condition is critical, doctors said.
According to the police, it was found during the initial investigation that Pinky Kashyap was preparing food when she noticed a gas pipe detachment, which then caught fire. Before the family could evacuate the house, the explosion occurred, resulting in the roof collapse on those inside.
The police reached the spot on receiving information and pulled out the victims from the debris. A fire department team was also rushed to the site.
The house collapse may have resulted in serious injuries to the victims, officials said.
