A religious teacher from a state high school in Madura, East Java, is likely to face sanctions after he was caught having sex with a married woman during Ramadan.

Fadilah, a local official, was quoted by state news agency Antara as saying on Friday that the married man had shamed the profession's image. An investigation had revealed that both the man and the women, a teacher also, were having an affair, he said.

The pair were caught during "social disease" raids over the holy month. Fadilah said the head of the district was yet to determine what sanctions the pair would face.
