SOFIA, April 18 (Reuters) - More than 20 Levski Sofia fans were detained after a policewoman was seriously injured following an explosion at the Vasil Levski stadium during the 26-times Bulgarian champions' league match against bitter city rivals CSKA on Wednesday. Reuters reported police chief commissioner Anton Zlatanov as saying a bomb had been thrown from the Levski fans' section, also injuring another police officer. "She underwent surgery but there are many pieces of glass on her face and in the eye," he said. "Such an act is inadmissible. It's not a firework or a small bomb, it's a bomb. This is an extremely unpleasant and ugly incident." He said the bomb had been thrown from the Levski fans' section at a door near one of the stadium entrances, adding that another police officer sustained minor injuries. "More than 20 Levski fans were detained but I can't tell the exact number," Zlatanov said. The Eternal derby, as matches between the two most popular clubs in the Balkan country are called, ended in a 2-2 draw. CSKA are second in the standings, eight points behind leaders Ludogorets. Levski are fourth. The derby, which finished in a 2-2 draw, has a history of crowd problems, with a man having died in a blast in 2000 and violence and arrests common. A man was killed by a bomb after the game in 2000 and hooliganism and arrests have been rife since then.
