MEXICO CITY (AP) — Four federal police commanders have been suspended from their posts in a violent Mexican border city following allegations from subordinates that they have links to drug traffickers.

The action by the Public Safety Department comes just hours after 200 federal police officers detained one of their superiors at gunpoint, alleging that he had connections to drug cartels and had participated in kidnappings, killings and extortion.

The Department said in a statement late Saturday that the commander held by officers earlier in the day was transferred to Mexico City along with three other officials. All will be investigated for "possible irregular conduct."

The four worked in Ciudad Juarez, a city across from El Paso, Texas, plagued by drug-related violence.
