The Department of Social Services launched an internal investigation against 24-year-old Michael Castro and has referred the matter to law enforcement, according to the agency.

The YouTube page "NYCreeps Spotlight", which poses as teenagers in an attempt to lure in pedophiles online.

"I put a fake profile up and I just wait for all these guys to hit my post up and in the beginning, I let them know my age, I let them know I’m 14-years-old. Some agree, some don’t agree, and the ones who agree, those are the ones that I catch," the creator told the New York Post.

The creator, who goes by "FM," applies filters to images from his adult female friends in order to make them appear younger.

He then arranges a date to meet in order to catch them in public and takes a video of the encounter and posts it to his YouTube page.

"These men are really disgusting, the things they say to these kids, the pics they send, it’s nasty," FM added.

Castro allegedly came across FM’s profile on the social media app Whisper in mid-August with a picture of  a 14-year-old girl named "Julie."

According to the video, Castro allegedly wrote she was "too young," adding that if she "were older I’d totally ask you out."

When Julie told him she had "no experience" with sex, Castro allegedly replied: "I’ll give you some" with a winking emoji and then added, "I’ll be gentle."

Following the incident, FM went to the Renaissance Shelter to further expose Castro, telling the residents what happened, the New York Post reports.

A spokesperson claimed Castro was "immediately transferred" as soon as they caught wind of the incident and said he "no longer has any contact with clients."

"The actions described are horrifying and will never be tolerated in our City. Ensuring a safe, supportive environment for clients, staff and community alike is our top priority as we help New Yorkers in need get back on their feet –– and we will not stand for any behavior that puts any New Yorker at risk," the spokesperson said. "Pending the investigation into the matter, we are prepared to take additional prompt disciplinary action."
