Mexican authorities have arrested a suspected top operator of the powerful Sinaloa drug cartel for whom the U.S. government had offered a $5 million reward.

Ovidio Limon Sanchez was detained this week in Culiacan, capital of the northwestern state of Sinaloa, Col. Ricardo Trevilla, spokesman for the Defense Secretariat, said Thursday.

Limon Sanchez, little known in his homeland, has been wanted for extradition since 2007 by the United States for cocaine trafficking and distribution.

Defense officials handed over the suspect, captured Wednesday by soldiers from the 9th Military Zone, to federal Attorney General’s Office agents at Mexico City’s international airport, the coronel said, adding that army troops detained Limon Sanchez in a carefully orchestrated raid without any shots fired.
