Ramiro Perez Moreno, a suspected leader of the notorious Zetas drug cartel, was captured early Monday in the border city of Nuevo Laredo.

The 34-year old Moreno was on Mexico's list of 122 priority targets for arrests.

The arrest occurred without any shots being fired.

Moreno is alleged to be a top operative of a criminal group operating in the border states of Coahuila, Nuevo Leon, and Tamaulipas.

According to The Associated Press, the statement of Moreno’s capture did not mention the Zetas by name but informed that the arrested individual was apparently in line to take over the criminal gang after the March 3 capture of Omar Trevino Morales, the alleged leader of the Zetas.

There is not too much known about Moreno, especially compared with other, higher-profiled cartel figures.

But what is speculated about Moreno's ties to cartel activity makes him sound like a very dangerous and powerful individual.

According to the navy, Moreno has trafficked drugs into the United States and brought arms back into Mexico. He has apparently waged wars on rival gangs and launched attacks on authorities. And he is supposed to have coordinated kidnapping, extortion and rackets were he smuggling people.

Weapons and drugs were confiscated during the raid in which Moreno was captured, and four other suspects were also arrested.

In recent years, the Zetas have a been behind a great deal brutal bloodshed along Mexico's northern border with the U.S..

It is believed that the Zetas currently control more territory than any other criminal gang in Mexico.

The cartel is known for their extremely violent methods, for decapitating rivals and even hanging their bodies from bridges.

But the notorious gang is going through a shift in power.

Last year, as reported by BBC, Mexican security officials announced that one of the founders of the Zetas, Galindo Mellado Cruz, had been killed in a gun battle in the northeastern state of Tamaulipas.
