"The investigation began in November 2011 and the operation involved 190 police officers. Thirty three people have been arrested and 57 others are being sought," Pazarlis told a press conference.
He said the criminal gang included two members of the Super League's security staff and six senior members of organized supporters clubs of PAOK.
Pazarlis said that the criminal charges included attempted murder, dangerous bodily harm, drug trafficking, damage to property and theft.
He said many of the gang members were identified through videos taken during attacks against police and supporters from other teams.
Pazarlis said that among the items found and confiscated during raids at seven clubs of organized PAOK fans on Tuesday were two pistols, a shotgun, three surgical blades, a cleaver, 40 cell phones, nine knives, a police radio, two axes, four baseball bats, a gas mask, 11 helmets, cash of 3,300 euros and U.S. 10,000 dollars as well as 348.48 grams of cannabis.
PAOK have refused to comment on the arrests.
