A 29-year-old woman, Emi Mamia, has been arrested and charged to court for slashing her husband's face because of his smelly 'poo', reports Japanese police.

The woman who has been charged for attempted murder, went into overdrive after her 34-year-old husband went to the toilet and the stench filled up the whole house.

Her anger was further fuelled when he tried to help their 3-year-old son use the toilet ‘without washing his own hands first’, and in the argument that ensued, the incensed woman used a kitchen knife to stab him in the face.

Japanese paper, Jiji reported her as saying:

"The toilet stinks so much that the child cannot even use it."
