Immigration and Customs Enforcement has arrested Antonio Israel Lazo-Quintanilla, a convicted killer and member of the 18th Street Gang, who was on El Salvador's most wanted list. His arrest drew attention due to a mugshot showing the numbers '666' tattooed across his forehead and other facial tattoos. Although his only offense in the United States was driving without a license, he is wanted in El Salvador for serious crimes including aggravated homicide and extortion. Officials have praised the arrest as evidence of ongoing efforts to target dangerous individuals, with the possibility of Lazo-Quintanilla being extradited to El Salvador. The incident comes amid increased immigration enforcement, with other high-profile arrests also reported recently.
