Mexico kingpin's arrest a victory that may fuel violence

MEXICO CITY (Reuters) - Mexico's government scored a huge victory with the capture of the country's most wanted drug lord but the cartels will remain a powerful force and could unleash a fresh wave of violence as they fight for control of his turf.

In a lightning raid early on Saturday, Mexican marines arrested Joaquin Guzman, whose dominance of the drugs trade and ability to elude the law since escaping from prison in 2001 had lent him almost mythical status.
