Police in Istanbul have detained 47 people in dawn raids linked to a corruption investigation that saw the city’s mayor imprisoned last month, leading to Turkey’s largest protests in more than a decade.

Among those arrested in Istanbul, the neighbouring province of Tekirdag and the capital Ankara were senior officials from Istanbul Metropolitan Municipality, local media reported.
