The Forest Preserves of Cook County confirmed that Officer Patrick Connor no longer works for the department following an incident filmed on June 14, which went viral almost a month later. A spokesman said the investigation into the incident continues and aspects of it will be further addressed, but offered no further information or details.
In the video of the June 14 incident, which has since been widely circulated online, Trybus is heard repeatedly questioning the woman's citizenship and told her she shouldn't be wearing her Puerto Rican flag shirt.
He added: "The United States of America is a nation that was built and thrives on diversity". VIDEO: Man harasses woman for wearing Puerto Rico shirt in Illinois Trybus is then seen asking her if she's an American saying, "Are you a citizen?"
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.
Later, she says: "Officer, I feel entirely uncomfortable, can you remove... please, officer" as the officer is seen walking away from her.
Irizarry asked why Connor would tell her brother to get back while allowing the aggressive outsider to continue to approach Irizarry and insult her.

'That officer did absolutely nothing he did absolutely zero, ' she says in the clip. More officers eventually arrived and arrested the man. But Conner resigned before investigators could ask him what happened during a disciplinary hearing, Pope said at a news conference Thursday.
Forest Preserve District Police Chief Kelvin Pope said Connor "should've stepped in, and he should've done something".
Connor was put on desk duty immediately after the incident, but nothing more was done for nearly a month. The video, posted on Facebook, has been viewed more than 1.2 million times. "You should be wearing United States of America flag", he said.
When the video started gaining media attention earlier this week, politicians including Puerto Rico's governor and Cook County politicians weighed in.
"(Conner's) personnel file will reflect that this officer did not resign in good standing, with a note indicating that he left the district with discipline pending", the park agency's general superintendent, Arnold Randall, said.
Preckwinkle called the video "completely unacceptable" and said she was "troubled" by the officer's response to the "terrible" incident. I've seen the video and I'm outraged that this would happen anywhere, let alone and especially sad that it happened in our forest preserve system.
And sadly, the same fear and "otherness" is extended to other people, the handicapped, gay and lesbian and transgender Americans, immigrants, Muslims, people of color the list just goes on. This is not the America we all believe in'.
