MIAMI (AP) — A once-standout U.S. federal narcotics agent known for spending lavishly on luxury cars and Tiffany jewelry has been arrested on charges of conspiring to launder money with the same Colombian drug cartel he was supposed to be fighting.

The FBI arrested Jose Irizarry and his wife, Nathalia Gomez-Irizarry, Friday at their home near San Juan, Puerto Rico, according to a law enforcement official familiar with the case.

In a 19-count indictment unsealed Friday, federal prosecutors in Tampa, Florida, accuse Irizarry of "secretly using his position and his special access to information"...
