ATHENS, Greece (AP) — The Greek soccer club Panathinaikos has been docked points and fined for fan violence last weekend that left 20 policemen injured and stopped a game against rival Olympiakos.

The Greek league said Friday it fined Panathinaikos $334,360 and deducted three points. The club will also play four home games without spectators and will start next season two points down. Panathinaikos remains second in the standings, 10 points behind Olympiakos.

Last weekend’s game was abandoned in the 82nd minute with Panathinaikos trailing 1-0. Olympiakos was awarded the victory.

Panathinaikos fans attacked officers with gasoline bombs and lit fires, damaging the scoreboard. Police made 20 arrests. Visiting fans had been banned from the game in a bid to prevent trouble.
