135 detained, 11 injured in fan violence around club match in Colombia

BOGOTA - Police say they have detained 135 people after fan violence left 11 people injured in Colombia.

Authorities said on Thursday three people were in serious condition after fans from America and Deportivo Cali clashed before, during and after the teams' match in the Copa Colombia on Wednesday in Cali.

The violence occurred even though fan groups from both teams agreed on a peace pact ahead of time.

Officials said a policeman lost a finger during the clashes.

Last Sunday, one man was shot dead and nine people were wounded in knife attacks after fans of Medellin rivals Atletico Nacional and Independiente fought each other and among themselves.

Police reported 315 arrests and confiscated more than 450 knives at the time.
