Fulson, 44, was in court Friday afternoon and is being held without bond. A judge cited his prior criminal history which includes sex crimes that date back to the 1990s. Back in 2001, he was charged with sexually assaulting a 14-year-old girl.
Police say Fulson has had over 30 arrests, including 11 felonies, since 1991.
Prosecutors say the charges involve students ages 15 and 16. They say the inappropriate sexual contact began with the 16-year-old in June 2016 and it ended last December.
Fulson allegedly recorded some of their 15 encounters.
He is facing criminal sexual assault and child porn charges.
The alleged underage victims include students at his Calumet Heights dance studio, Final Phaze Performance Dance Troupe, located in the 1700 block of East 87th Street.
Right now prosecutors say there are five other open cases involving Fulson and minors at his dance studio.
Parents of students at Final Phaze spoke out out in support of dance instructor Maurice Fulson Friday.
One parent said she doesn't believe the accusations.
"We all trust our kids around him," said the mother.
Because of the charges, the board of directors of Final Phaze has removed Fulson as their CEO.
"We were devastated to hear the allegations and we do not support any act of violence against any person whether youth or adults," said Angela Hongo, Final Phaze Board of Directors.
"He deserves as much punishment that the state will allow, that the court will allow, he deserves every bit of it," said Danielle Bonds who works in the area.
"What can you say, you never really know anybody well enough. Especially if you come over here and you just do business, and at the end of the day you just go where you go, you don't really get a chance to know anybody too well," said Yoel Harris who works near the dance studio.
Some believe there could be even more victims.
"If you have young ladies who are scared to voice it or scared to tell or embarrassed, it could take forever," said Bonds.
According to Chicago Public Schools, Fulson taught students on at least three occasions with an after school dance program through an outside vendor. CPS is not aware of any allegations involving their students.
Final Phaze board members say the dance troupe still plans to take part in the Bud Billiken Parade Saturday.
"It seems very unfair to punish them for something that someone may have or may not have done in their personal life. This does not affect the children, you are only punishing them," said Hongo.
Fulson is due back in court on August 29.
