Shots were fired at the house of Ayhan Sefer Üstün, deputy chairman of the opposition Gelecek Party, in the northwestern province of Sakarya on Tuesday, Turkish media outlets reported.
A statement released by the party said the assailant has a criminal record due to involvement with a gang and was involved in similar attacks in the past.
Nobody was injured in the attack as Üstün was in Ankara with his family. The assailant, identified only by the initials as S.A., was detained by the police.
Üstün, who was a former Justice and Development Party (AKP) member, had recently joined the Gelecek Party, which was established by Ahmet Davutoğlu, a former prime minister and AKP heavyweight in December 2019.
