WARSAW, Poland (AP) -- Polish police say they have arrested six people suspected in an attack by hooligans on a train.
The six suspects were being questioned on Sunday, a day after the incident involving dozens of people. Police say it appears to be related to a feud between rival hooligan groups.
Late Saturday, black-masked hooligans attacked a train traveling between the northern Polish cities of Elblag and Gdynia. They threw stones, breaking windows of the train before boarding it and attacking passengers. One person lost consciousness and four others were slightly injured.
Polish media reported that some of the passengers were martial arts fans traveling to a competition.
