REUTERS/Carlos JassoMEXICO CITY, June 16 (Reuters) - A Norwegian company has found six "deficiencies" in the construction process that contributed to the collapse of the Mexico City metro last month, according to contents of a leaked report published by a leading Mexican newspaper on Wednesday.
El Financiero newspaper said the preliminary report into the crash that killed 26 people, compiled by Norwegian external auditor DNV, cites structural failure associated with at least "six deficiencies in the construction process".
El Financiero said the 58-page report cited welding of bolts, including unfinished or poorly executed welds, as well as deformation of the beams, among the deficiencies.
Mexican billionaire Carlos Slim, Latin America's wealthiest man and Lopez Obrador ally, has also faced pressure over the crash as his construction arm Grupo Carso was involved in building the section that collapsed.
