MANAGUA, Nicaragua (AP) -- Nicaraguan authorities say a bus driver hired to transport supporters of the governing party is suspected of helping plan attacks which killed five people.
A judge on Saturday ordered Walter Balmaceda held pending an investigation into charges of conspiracy.
On July 19, gunmen shot at buses carrying members of the Sandinista National Liberation Front after a celebration marking the 1979 ouster of the Somoza dictatorship. Three other men are accused of accepting payments to throw rocks at the buses to slow them down for the gunmen, who remain unidentified.
Balmaceda denied the charges, telling reporters, "the only thing I did was transport people. ... I had nothing to do with this."
Gonzalo Carrion of the non-governmental Nicaraguan Center for Human Rights criticized the investigation, which he said is targeting "scapegoats."
