Unidentified suspects painted a Nazi swastika on the memorial of Turkish murder victim Burak Bektas, Berlin police said on Thursday.
An investigation is opened after a witness noticed the swastika on the memorial and informed the authorities, the police said in a statement.
Burak Bektas was shot to death in 2012 while chatting with his friends on the street. The murder still remains unresolved.
His family and friends have repeatedly called for a deeper investigation into the murder, stressing that witness testimonies indicate that he was killed by a right-wing extremist.
The memorial was built in 2018 in a park at the junction of Rudower and Mowenweg streets in Neukolln district.
