    Key details

  • • Mexican authorities announced the arrest of Mikael 'Greken' Tenezos, a Swedish gang leader.
  • • Swedish prosecutors have not yet confirmed the arrest and await information from Mexican officials.
  • • There is no formal extradition agreement between Sweden and Mexico, but Tenezos is held for possible transfer to Swedish authorities.
  • • Criminologist Manne Gerell suggests that the arrest of gang leaders may reduce violence due to decreased financial backing of conflicts.
  • • Swedish and Mexican authorities have been cooperating effectively in investigations involving Tenezos.

Mexican authorities announced the arrest of Swedish gang leader Mikael 'Greken' Tenezos on Saturday, bringing attention to a key figure involved in several ongoing investigations in Sweden. As of October 12, 2025, Swedish police and prosecutors have neither confirmed nor denied the reports of his arrest. Prosecutor Ida Arnell, leading one of the cases against the 27-year-old in absentia, stated she had not yet received information from Mexican officials regarding the arrest. It remains unclear whether Tenezos was detained for crimes committed in Mexico or based on an international warrant. However, Mexico's security agency reported that he is being held for possible transfer to Swedish authorities. While Arnell did not speculate on extradition details, she expressed optimism about Mexico's willingness to cooperate. State prosecutor Daniel Jonsson, also involved in cases against Tenezos, highlighted the arrest's significance, citing strong suspicions against him in multiple investigations and praising the cooperation between Swedish and Mexican authorities, although he did not disclose specifics.

The arrest of Tenezos comes amid a situation where two out of three identified Swedish gang leaders are now incarcerated, indicating a notable disruption in gang leadership. Criminologist Manne Gerell noted that the absence of these leaders might create a power vacuum within the gangs but suggested this could lead to a decrease in violence. He explained, “Violence decreases when a person stops pouring money into the conflict,” highlighting the role of financial backing in sustaining gang-related violence.

This development is viewed as potentially positive from a crime prevention perspective, as weakening leadership could reduce violent conflicts tied to these gangs. The reported arrest in Mexico, pending official confirmation from Swedish authorities, marks a critical juncture in ongoing efforts to tackle organized crime involving Swedish nationals abroad.
