Authorities in northern Mexico are looking for two distribution employees of a national newspaper who were reported missing earlier this week.
The daily newspaper El Financiero says the two men were traveling in the northern state of Zacatecas, and last reported they were being followed by "two patrol cars."
A statement from the Zacatecas state government Wednesday says federal and local police are searching for the two men. It notes that criminals in Mexico sometimes use fake patrol cars for highway robberies and other crimes.
Mexican media organizations and journalists have come under a rising number of attacks in recent years as drug cartels have confronted government forces.
