A minor league baseball coach in Manhattan claims a squad of ICE officers approached members of his team while they were practicing in Riverside Park.

Yeoman Wilder, the founder of Harlem Baseball Hitting Academy, was instructing middle and high school students on July 3 when he claims six ICE officers went through the Upper West Side park, passing the basketball courts, according to reports.

"But I didn't think much about it. I simply figured, oh, they're ICE officials, since I've seen them in Washington Heights before," Wilder explained.

 But then he claims they approached the children and began asking questions.

"Where they're from, who are their parents, and I just thought, 'Whoa, whoa, this is... this is not good,'" Wilder said.

Wilder has a master's degree in law and informed them they didn't have to answer such questions.

"I told my kids to walk to the back of the cages, right here, and I said they're going to invoke their fifth amendment rights, they're not going to say anything," Wilder said.

He says one of the officers began to get aggressive. 

"That's when I was called a YouTube lawyer, and I said, 'No, I just know how the Constitution works,'" Wilder said.

 All of the children, Youman claims, are American citizens.

"Their parents are from the Dominican Republic, South America, Mexican, Africa, but their kids were born here," Wilder said. "They have a 14th amendment entitlement to live here."

 Wilder claims they were armed and in uniform. 

"They looked like the real thing," Wilder explained. "From what I've seen in Washington Heights and what I saw that day."

He's contacted local political authorities, including Assemblymember Linda Rosenthal, who thinks he was correct to inform the children of their rights.

"No one has the right to take you away or to get any of your information," Wilder said.  "I've never in my life thought this was going to happen on the Upper West Side, in New York City. That whole thing, until it happens to you, you're not aware. And it happened to us."
