The body of a man has been found in toilets in a shopping centre in King's Lynn.
The man, who has not been named but is believed to be in his 30s, was found in the men's toilets at the Vancouver Centre just before 1230 GMT on Monday.
A police spokesman said a woman, also in her 30s, was found unconscious.
She was taken by ambulance to the Queen Elizabeth Hospital in King's Lynn for treatment.
A post-mortem examination would be carried out on the dead man and the coroner had been informed.
