During the encounter, a Cook County Forest Preserve District police officer can be seen standing by and doing nothing as Irizarry asks for help.
"We are further addressing aspects of this incident and more information will be shared here and with the media tomorrow (July 12)".
In a now viral-video shot on June 14, an irate approaches Mia Irizarry as she waited for her family at a picnic area in the Forest Preserves of Cook County to celebrate her 24th birthday. "Are you a United States citizen?"
In the video, Trybus could be seen telling the woman that she should not be wearing the T-shirt in the United States, despite her attempting to explain that Puerto Rico is a USA territory.
Mia Irizarry posted a Facebook video of the alleged incident, appearing to show a man, later identified by the department as Timothy Tybus, approaching her and criticizing her T-shirt, which is designed with the Puerto Rican flag. She said she was thankful officials recognized the behavior of the officer was wrong.
Ms Irizarry asks a park police officer who has arrived for help, saying: "I am renting this area and he's harassing me about the shirt that I'm wearing". Timothy Trybus was originally charged with simple assault for the incident, but this week, the Cook County State Attorney's Office announced that he would also be facing a felony hate crime charge.More news: Croatia 2-1 England: 11 things we learned

PHOTO: The first officer on the scene did not appear to intervene and has since been placed on desk duty. She said it took two hours before officers arrested Trybus for disorderly conduct.
'That officer did absolutely nothing he did absolutely zero, ' she says in the clip. But Conner resigned before investigators could ask him what happened during a disciplinary hearing, Pope said at a news conference Thursday. These angry outbursts and attacks do not represent our values here at the Forest Preserve system and in Cook County, and are not representing who we are as a country. I am troubled by the initial response by the officer who was on the scene.
I showed my official ID as a Member of Congress, to which the officer said, "I don't think so", indicating that she thought my ID was a fake and that I couldn't possibly be a Member of Congress.
By now most of us have seen the video of that incident.
A police officer who failed to step in has also resigned amid backlash.
The incident had drawn an immediate backlash, with a number of local politicians and some from Puerto Rico condemning the attack. "Are you a United States citizen?" he screamed, referring to the shirt as "un-American". "People have just as much right to be here as you do, and when you're drunk you don't belong here". Spencer, speaking about America, told the Los Angeles Times in 2016: "We live in a multi-cultural country where now, European Americans are being dispossessed".
Meanwhile, the Forest Preserves issued its own apology for what happened.
