A Singaporean tourist was nabbed in Miri, Sarawak, for running topless on Sunday, reported Sin Chew Daily.
Police apprehended the woman after the public alerted them.
She was taken to Miri Hospital.
When police questioned the woman, who is in her 40s, she said she was only doing her daily exercise and was used to running topless when she lived in Britain.
Her Caucasian husband, however, told police the woman had mental illness.
Police did not press charges against the woman but issued her a warning.
