An Indian national studying in the United States on an F-1 student visa, Varun Batchigari, has been arrested in Berlin, Germany, and faces extradition to Arizona over the murder of his girlfriend, University of Arizona student Julissa Salazar. The case has drawn attention because Salazar's mother says Batchigari was known to be a "threat" following a prior arrest, raising questions about whether the earlier warning signs were adequately acted upon before the killing.

Fox News reports the suspect fled the US after the alleged killing before being apprehended in Germany, with a former Department of Justice prosecutor noting the international legal hurdles involved in bringing him back to face charges. Officials have also flagged Batchigari's status as a repeat offender who had prior contact with the justice system, and the case is being cited alongside other recent stories involving foreign nationals on student visas accused of violent crimes in the US.
