Police officer Cahit Sen, who was found not guilty after being arrested for allegedly using ByLock, contracted cancer while he was in prison. Sen, who filed a lawsuit and won 31,544 Turkish Liras compensation, died before he could see that the decision was finalized.

Police officer Cahit Sen, who works at the Traffic Registration Branch of the Erzincan Provincial Police Department, was suspended from his post three days after the July 15 coup attempt on the grounds that he used ByLock. Sen was arrested on September 6, 2016 on charges of membership of Hizmet Movement and retired while in prison. Sen was released on March 14, 2017, after it was revealed that he had been charged with ByLock for using the internet line in the house jointly with a police officer. He was acquitted on November 28, 2017, in a trial at the Erzincan 1.Criminal Court.


Cahit Sen filed a lawsuit on the grounds that he was wrongfully arrested. Sen, who stated that he had cancer while in prison, where he stayed for 6 months and 12 days, said in his petition: “I was excluded because I was a bylock user. My parents are left alone. I got cancer from sadness and stress, from unfavorable conditions in prison. There was an acid factory next to the prison. We had to inhale the smoke coming out of here. We were hanging our clothes in the ward because it was cold. Combined with the dirty air, the smell of detergent and sadness, I contracted the disease. I was diagnosed with lymphoma.”

On March 27, 2019, the court found Sen right, he received financial compensation of 1544 Turkish liras and moral compensation of thirty thousand Turkish Liras. Sen, who was undergoing treatment while his case was ongoing, died on May 21, 2019. Sen could not see that the decision had been finalized. Sen’s daughter, Zuhal Gokce Sen, said, “We have no financial expectations. We’re not even following the case. I don’t want my father’s death to be passed off as if it were any event. I want it to be known what happened to him, how he was wronged”.
