Authorities intercepted communications in which the criminal group leader described a tunnel project in San Isidro. In the same recordings, he mentioned a planned robbery targeting a street food stall in Chivilcoy. The suspect, identified as Eduardo Riva, was summoned for questioning by prosecutor Patricio Ferrari. Riva declined to give a statement when the prosecutor sought his testimony. Investigators are compiling further details about the alleged plot. The case remains active as law enforcement follows the leads uncovered in the intercepted audio.
