From BBC News:
Naomi Coleman was arrested as she arrived at the airport in the capital Colombo after authorities spotted the tattoo on her right arm.
A police spokesman said the 37-year-old from Coventry was arrested for “hurting others’ religious feelings”….
Ms Coleman is being held at an immigration detention camp after a magistrate ordered her deportation.
She is expected to be removed within days.
Sri Lanka is particularly sensitive about images of the Buddha….
Ms Coleman said there was initially no problem with officials but two taxi drivers and a plain clothes police officer told her she was breaking the law and brought her to a police station to make a statement.
