Italian Interior Minister Giuseppe Pisanu said the raids had dealt "a hard blow to the most powerful and ruthless Italian criminalorganisation, " French news agency AFP reported.
Officials will only confirm that they had been paid to perform at an event when members of a criminalorganisation appeared and abducted the musicians at gunpoint.
"The Mexican authorities need to ascertain whether or not any state officials ... were complicit with the criminalorganisation that carried out the abductions and extortion, both in this and other cases, " she added.
