At least 17 people were detained as part of an Aksaray-based investigation into the Gulen movement, which the government accuses of masterminding the July 15,2016 coup attempt, on Tuesday.
An Aksaray prosecutor issued detention warrants for 18 individuals who were earlier removed from their jobs under post-coup emergency rule.
Police carried out operations in Aksaray and Hatay provinces where 17 of the suspects were rounded up.
The detainees consist of doctors, nurses and hospital technicians.
Police still seek for the remaining suspect.
Turkish government has already detained more than 126,000 people and arrested over 55,000 for ties to the movement since the summer of 2016.
