The incident occurred when the family of one Arvind Kumar, along with his friends, was holding a condolence meet of his grandfather under the roof amid rains on Sunday afternoon.
Around 50 people had assembled when suddenly the roof caved in burying almost everybody. Kumar too died in the incident.
Use of inferior quality building material is said to be the reason for the incident as the roof was constructed just six months back.
BSP president Mayawati has demanded strict action against the responsible officers and others in the incident besides adequate compensation for the kin of the deceased.
The UP government has already announced a relief of Rs 2 lakh to the families of the deceased.
