The men of the Ondo state Police Command has arrested a 30-year-old woman, Blessing Jimoh, for allegedly killing her mother, Ijeoma Odo.
Blessing said she killed her mother with a cutlass after a Pastor said her mother was a witch, the Nation reports.
She was paraded alongside other criminals.
The Pastor is said to be on the run.
Blessing said she has four children and committed the crime while they were working at the farm Ile-Iluji area.
She claimed to be mentally unstable when she committed the crime.
