The United Nations said Monday it has captured a Haitian gang leader wanted in the killing of family members of two cohorts who had agreed to join a disarmament program. On a routine patrol Sunday night, peacekeepers arrested Johnny Pierre Louis in the seaside slum of Cite Soleil, the UN mission said in a statement. Louis, also known as Ti Bazil, will be turned over to Haitian national police, UN spokeswoman Sophie Boutaud de la Combe said. The arrest came 10 days after hundreds of UN troops raided Cite Soleil to dislodge armed gangs, which are blamed for a string of kidnappings and killings in the Haitian capital of Port-au-Prince. At least one gang member was killed and four wounded.
