Greek authorities on Thursday announced the names of 15 people suspected for 'fixing' matches in the Greek first division 'Super League' championship, including club owner Makis Psomiadis and coach Yiannis Papacostas.

The scandal was uncovered after the European soccer federation UEFA noticed irregular betting patterns involving first- and second-division club matches.

First-instance court prosecutor Popi Papandreou released the names of those involved, including 10 people arrested on Wednesday night and another five for which arrest warrants were issued but are not in custody.

The names released by authorities include those of Achilleas Beos, Giorgos Tsakoyiannis, Nikolaos Zamanis, Vassilios Karakoulias, Andreas Dimopoulos, Dimitris Zavantias, Athanassios Dotsis, Nikolaos Halkos, Nikolaos Pantelis and Stavros Psomiadis, all of whom were arrested on Wednesday.

The five not currently in custody are Chrysostomos (Makis) Psomiadis, Ioannis Papadopoulos, Vassilios Geortsiakos, Mihalis Nikolopoulos and Yiannis Papacostas.

The charges against them include forming a criminal organisation and running a criminal organisation, fraud as a habit and occupation, involving sums in excess of 15,000 euro, repeated counts of habitual and occupational extortion with the threat of harm to the career of the victim, bribery to alter the outcome of a match, repeated counts of illegal betting, repeated counts of participation in illegal betting, instigating the previous two offences and illegal weapons possession.

After the charges were read out, the case was sent to the 9th examining magistrate, who is expected to call in an additional 70 people for questioning as suspects for which authorities do not currently hold sufficient evidence to justify their arrest in the act.

Sources within the justice system revealed that the investigation into the case was originally launched in October 2010. The assistance of Greece' National Intelligence Service - but not the police - was sought in January this year after an anonymous report containing the specific names reached the Paleo Faliro police department.
