A woman who suspected her husband of cheating with their maid marched their pet parrot to police after it began spouting saucy lines she knew hadn't been said to her.

She believed the parrot had exposed her husband's secret trysts, which are illegal in Kuwait where they lived, Al Shahed Daily reports.

The woman took the parrot to police and filed an adultery complaint against her partner.

However, the authorities ruled the parrot's evidence was inadmissible because it was impossible to determine where the bird had heard it.

They argued he could have picked up the scandalous lines from television or a radio show.
