Mexico dissolves U.S.-trained special unit fighting drug cartels after it was "infiltrated" by criminals, president says

Mexico has dissolved a special unit trained by U.S. authorities to fight drug cartels because it was infiltrated by criminals, President Andres Manuel Lopez Obrador said Thursday. Some members of the group have been detained over the allegations, Lopez Obrador told reporters.

The police unit, which received training from the United States Drug Enforcement Administration, was disbanded more than a year ago, but the decision was not announced at the time.

"There's still cooperation (with US authorities) but that group that was supposedly of a very high strategic level was infiltrated (by organized crime) and its leaders are being investigated," Lopez Obrador told reporters.
