Former Turkish minister Fatma Betül Sayan Kaya was arrested in an investigation into alleged price manipulation. She is suspected of violating capital-markets law and belonging to a criminal organisation. Her husband, Ilyas Kaya, was released under judicial supervision and is barred from leaving the country; the couple deny wrongdoing.

Investigators said Kaya had non-public information that could affect the value of investments. She is alleged to have bought shares in April and sold them on 16 September, a day before the regulator abolished the funds concerned. An opposition representative had previously alleged that the couple made about €38 million from share sales. Kaya, formerly a vice-president of the ruling AK Party, resigned from that post in September amid the scandal.
