TAMAULIPAS, MEXICO (KGNS) - A total of 22 passengers were kidnapped by armed men from a bus in northern Mexico last week.
Authorities say the gunmen had let the rest of the passengers go unharmed after intercepting the bus in the northern state of Tamaulipas last Thursday.
Mexican officials have not been contacted by any family members of the missing who are believed to be migrants.
State Security spokesperson Luis Alberto Rodriguez said in an interview that authorities had registered 22 people missing, three more than previously reported.
Mexican President Andres Manuel Lopez Obrador said on Tuesday that investigations remain ongoing to determine what happened including whether the abduction was in fact a means to cross the border into the U.S.
