The American-born son of Mexico’s most notorious drug lord has been handed over to US authorities — bringing a close to a lengthy court battle touched off by the scion’s 2015 arrest, court records show.

Rubén Oseguera-González, also known as “El Menchito,” was extradited Thursday and is being held in Washington, DC, where he is expected to appear in court on Feb. 27, according to papers filed in federal court.

Oseguera-González is the son of Nemesio “Mencho” Oseguera-Cervantes, the alleged leader of the bloodthirsty Jalisco New Generation Cartel, NBC News reports.

The cartel is now considered Mexico’s most powerful drug organization and the US Drug Enforcement Administration is offering $10 million for information that could lead to Mencho’s arrest.

The leader’s son faces charges that he trafficked cocaine and meth in the US and brandished firearms to ply his trade, court records show.

But the junior Oseguera-González’s extradition to American authorities has led to retaliation, The Associated Press reports.

The US Embassy in Mexico City issued a security alert on Thursday stating that “criminal groups operating in Jalisco have responded by taking retaliatory actions including an increase in anti-government rhetoric (banners and internet threats) and blockades inside the city and on interstate highways.”

“On some occasions, these criminals have seized private vehicles and set them on fire,” the alert reads.

The Jalisco New Generation Cartel is a relatively new player in Mexico’s drug-trafficking scene. It was founded in 2011 yet quickly shot up in the ranks — the DEA estimates that its influence reaches to about three-fourths of Mexico’s states, NBC News reports.
