Federal prosecutors in Mexico have charged the son of a former governor in a crime-wracked western state with withholding evidence about a video that purportedly shows the son meeting with a leader of a drug cartel.

A statement Sunday from the Attorney General's Office says Rodrigo Vallejo has been charged with the "crime of concealment from a district judge." The statement says Vallejo refused to testify Friday about the video.

In the video made public last week, Vallejo sits with a man identified as Servando Gomez, the alleged leader of the Knights Templar cartel based in Michoacan state.

Vallejo's father is former Michoacan Gov. Fausto Vallejo, who resigned the post in January, citing ill health. Federal authorities have taken control of security in the state.
