Rome, N.Y. -- When John Collins ran to his milk house because he heard yelling Wednesday morning, he opened the door to find "scruffy guys" who were armed pressing one of his workers' faces to the glass.

They were not wearing anything that indicated they were officers with Immigration and Customs Enforcement, Collins said. They did not identify themselves to Collins before they came on his property. And when he asked them to show him a warrant, they gave him nothing, he said.

In a video shot by Lillian Jeng-Wheeler at Collins' house Wednesday, Collins described what happened when ICE agents came on his farm Wednesday. Jeng-Wheeler is an immigration advocate.

ICE officers ended up detaining one of his workers, Marcial de Leon Aguilar. They also took Collins' phone when he tried to video them, threw it across the road and put him in handcuffs, Collins said.

A Syracuse.com story about the incident led U.S. Sen. Kirsten Gillibrand, D-NY, to call for a federal investigation into the incident.

Aguilar was taken to the Buffalo Federal Immigration Detention Center in Batavia.

A spokesman with ICE, contacted multiple times by Syracuse.com, has said the agency is looking into what happened but has not provided any comment so far.

Collins said it appeared the the ICE officers who detained Aguilar weren't certain who he was. He again asked the officers for documentation, but they gave him none.

"You don't know who he is. You have no clue who he is," Collins said he told the officers. "You can't just take someone and grill them because of the color of their skin."

Aguilar's wife, Virginia, entered the country illegally four months ago with their four children and was caught crossing the border. She's been working with immigration officials to apply for asylum. She is also pregnant, and wearing an ankle bracelet tracker at the request of ICE. The family lives in a house on Collins' property.

Virginia was at a doctor's appointment when her husband was detained, Collins said. He began to cry in the video when he described her finding out.

"To see Virginia come out of her car .. to see her break down (and fall) to her knees," Collins says, his voice breaking. "She's saying why didn't they take me. Why did they take him?"
