Las Vegas Police Arrest Man for Threatening Mass Shooting at Sporting Event.

Las Vegas police arrested Matthew DeSavio, a 33-year-old man with a history of mental illness and arrests, for threatening to carry out a mass shooting at T-Mobile Arena, the venue where the Golden Knights would capture their first championship. DeSavio had threatened to "shoot up" the hockey game against the Florida Panthers in a massacre that would rival the October 2017 mass shooting on the Strip. He faces charges of threatening an act of terrorism or mass destruction, aggravated stalking, and violating a restraining order.
