A group of 32 armed Venezuelan nationals reportedly took control of an apartment building in Chicago on Monday night, according to a 911 dispatch call and local sources. The audio, which has been widely circulated online, captures the chaotic scene as residents desperately called for help, leading to heightened concerns over the rise in migrant-related crime in the United States.

That’s what a post shared Elon Musk said today. Chicago police have confirmed the 911 call as being authentic but said when police arrived they found no evidence of the reported incident.

The alleged takeover in Chicago follows a similar incident in Aurora, Colorado, where a group of Venezuelan migrants reportedly seized control of a building. Although there is no video footage from the Chicago incident, the 911 audio has been verified by local authorities, who confirmed that law enforcement responded to the situation and found no evidence.

police did not say whether it was a swatting incident at this time.
