Turkish Twitter users sounded the alarm after police raided the headquarters of an opposition-linked media group on Wednesday morning.

Wielding batons and armed with a water cannon and tear gas, police stormed the Istanbul office of Koza-Ipek media group, arresting journalists and dispersing protesters who were gathered outside. The company has ties to a US-based cleric named Fethullah Gulen, a prominent opposition figure and adversary of President Erdogan. 

Koza Ipek's television station, Bugun TV, was broadcasting live as police broke through the gates of the media compound. Video footage filmed at the scene shows the moment authorities entered the building.
