The Hennepin County attorney's office originally had expected to file charges Friday afternoon, but prosecutors said about 4 p.m. that they want more time to investigate the complex case.
Bruley said that Manito was able to access the high school by deceiving security before going to meet the student in a bathroom.
Dixon Police say there is no information to suggest the student planned to harm anyone at the school.
Shirola says he initially called his mother to report the bathroom incident, but 30 minutes later he saw the man again wandering the halls.
In an email sent to parents in the district, Principal Mike George said the man entered the school Wednesday with the intent of meeting a student and that the man "violated our safety procedures to do so". He was in the school for about an hour before he was caught by school officials.
The suspect was arrested for criminal sexual conduct and is being held at the Brooklyn Park Jail.
The question remains whether or not Manito committed a crime, as the student is an adult.
At a Friday press conference, Brooklyn Park Deputy Chief Mark Bruley said both Manito and the student were cooperating with investigators. Little is known about the suspect, he doesn't even have a Minnesota driver's license.
Dixon Police now have School Resource Officers assigned to Dixon High School and Reagan Middle School, and Chief Langloss said in a statement that helped them resolve the potentially unsafe situation.
The Anoka-Hennepin School District upped security measures after the breach.
