A simple bump quickly escalated into an aggravated assault outside of the Recreation and Wellness Center, police said.
Officers responded outside the gym after a man, Diego Villavicencio, a UCF student, allegedly threatened another student with a pocket knife on March 22, an arrest affidavit said.
Sadie Mercedes was walking outside of the RWC when Villavicencio, 25, bumped into her. 
Mercedes told police she wanted an apology, and when Villavicencio wouldn’t apologize, she got her boyfriend involved.
“Excuse you, you just bumped into me,” said Mercedes to Villavicencio.
After Villavicencio told Mercedes that she should have moved out of his way, her boyfriend chimed in telling the him to just say sorry.
That’s when police say Villavicencio pulled out his pocket knife and said that today was not the day to mess with him, the arrest affidavit said. Police say Villavicencio waved the knife at the girl’s boyfriend and said “I don’t feel like doing this right now.”
Mercedes and her boyfriend called police and officers were able to find Villavicencio using surveillance footage and biometrical reader at the RWC.
Villavicencio was was taken to the Orange County jail and is being held on a $1,000 bond.
