The woman, who suffered 95 per cent burns, was admitted to the district hospital from where she was referred to Meerut for treatment.
According to police, the brick kiln owner, Aas Mohammad, along with another man sprinkled Kerosene oil and set her on fire after she resisted an alleged attempt by them to rape her on Wednesday evening.
A Sub Inspecter, who was sent to record her statement, reported that the victim had sustained burns while working at the kiln.
The accused have been arrested and sent to jail, police said.
