Protests broke out in Austin, Texas, on Sunday after a US Immigration and Customs Enforcement (ICE) officer shot and injured a Venezuelan delivery worker.
Wilber Rafael Garces Perez, 28, was struck in the torso and transported to hospital, according to his attorney.
His lawyer, Kate Lincoln-Goldfinch, said the DoorDash driver later contacted his wife while in severe pain.
The US Department of Homeland Security (DHS) confirmed that authorities were investigating the incident.
The department said the man had entered the United States illegally, but officials have not disclosed what triggered the shooting.
The circumstances surrounding the confrontation remain unclear, prompting Austin Mayor Kirk Watson and local law enforcement officials to call for an independent investigation.
Several dozen demonstrators gathered near the location, with some carrying Mexican and Guatemalan flags and placards calling for ICE operations to end in the city.
Television footage showed protesters assembled opposite a damaged blue Toyota Corolla while immigration officers remained at the scene.
Mayor Watson said residents deserved a clear account of the incident and should feel secure in their community.
He also noted that ICE activity in Austin had increased considerably in recent weeks.
The latest shooting follows another fatal incident in Houston involving an ICE officer.
DHS previously said Lorenzo Salgado Araujo was killed during an immigration traffic stop, although he was not the subject of an ICE investigation.
Texas Democratic Congressman Greg Casar has called for an immediate independent inquiry and urged officials to release body-camera recordings.
He also demanded consequences for any officer found to have violated the law.
Immigration rights groups have accused the Trump administration of undermining due-process protections through its intensified enforcement campaign.
Democrats have also called for changes within ICE, including mandatory body cameras and visible identification for agents.
Earlier this month, the Justice Department charged an ICE officer with allegedly making false statements concerning the non-fatal shooting of a Venezuelan migrant in Minnesota.
Meanwhile, Republican Florida Representative Maria Elvira Salazar has criticised the detention of immigrants without criminal records.
Appearing on CBS’s Face the Nation on Sunday, she said she had spoken with President Donald Trump and remained confident in his approach to immigration policy.
