Following the fatal stabbing of the antifascist rapper
Pavlos Fyssas on 17 September 2013 by a supporter of his party, Michaloliakos was arrested in a 28 September 2013 sweep, along with numerous other Golden Dawn leaders on the charges of allegedly being involved in a criminal organisation. The charge sheet included murder, extortion, and involvement in the disappearance of up to 100 immigrants. After 18 months of pretrial detention, the maximum allowed, Michaloliakos was released from jail and placed under
house arrest. On 29 July 2015, his house arrest was lifted, but he was prohibited from leaving the
Attica region. In April 2015, the trial of Michaloliakos and 68 other defendants began at the high-security Korydallos prison in Athens, but was adjourned a number of times for technical reasons and to find a more suitable setting. Michaloliakos was one of 68 Golden Dawn leaders who were found guilty in October 2020. He was sentenced to 13.5 years in prison but was granted early release in May 2024 following a legal request and on account of his elderly age, albeit with several conditions such as a ban on traveling outside the greater Athens area. However, his release was subsequently overturned by another panel of judges following an appeal that found that he had shown no repentance for his crimes and was capable of reoffending. This led to him being rearrested in his residence in Athens on 3 June. On 12 September 2025, a judicial council allowed Michaloliakos to serve his sentence at his residence on grounds of ill-health. ==Personal life==
