Turkish police on Wednesday arrested 25 people they accused of using Twitter and social media to stoke anti-government sentiment during protests that have engulfed the country. Police in Turkey’s third city of Izmir said the suspects had been detained for “spreading untrue information” and inciting people to join demonstrations, the state-run agency reported. They were rounded up on Tuesday night. Izmir, in western Turkey, has been the scene of violent clashes between riot police and protesters. The authorities appear to have taken their cue from Turkey’s prime minister, Recep Tayyip Erdogan, who denounced Twitter as a “menace to society”, adding: “The best examples of lies can be found there.”
