The victims are mostly teenagers and, in some cases, unsuspecting school administrators.
Philip Cataldi, who was working for Davis, said he thought something wasn't right and decided to research his name on the internet.
He found the exclusive Eyewitness News stories about Davis' alleged past scams on 7online.com.
He then contacted police, who were able to place Davis into custody at a Dunkin' Donuts in Cherry Hill Sunday afternoon.
Just last month, Davis allegedly talked his way into Hoboken High School. He said he had jobs for some of the students.
They then raised money for a raffle that didn't exist. Davis allegedly took the cash and bolted.
Eyewitness News caught up with him a couple weeks ago at Manhattan's Star Career Academy, but he took off running. It's a vocational school and Dr. Davis' latest stop on tour of schools allegedly looking for unsuspecting students to con.
However, his scam didn't work at the Star Career Academy because school official Ross Freidman did a little research.
"I did a search online found your story," Freidman told Eyewitness News.
It was the story Eyewitness News did in Hoboken last month and other articles about Davis.
Authorities say he's a man with the fake business cards for a company that doesn't exist with promises for students that never pan out.
He ended up getting away from our Eyewitness News crew that day and police, but that all changed on Sunday.
Davis will remain in Cherry Hill until Hoboken police can arrange to get him.
