London police discovered a woman's corpse in a home freezer 20 years after her death and were questioning her 83-year-old daughter, Britain's Press Association reported.

Police searched the home of Daulat Irani 10 days after a neighbor reported that there might be a body in the garage, the agency said. Police believe the dead woman, Gulbai Freedoon Murzdan, died 20 years ago.

Police confirmed they were investigating the incident, but declined to comment on any relationship there might be between the dead woman and the woman being questioned.

Britain's Daily Mirror newspaper reported Wednesday that Murzdan's daughter hid her mother's body in the freezer wrapped in a black trash bag.

The newspaper said Murzdan had been living in the country illegally and that her daughter feared immigration authorities.

Police said they are treating the death as unexplained and will conduct an autopsy on Friday.
