Lucy Usoyan does not remember all of the details of the brutal beating she suffered at the fists and feet of a group of men in front of the Turkish embassy in Washington, D.C. on May 16.

But after being shown a picture of Eyup Yildirim, she says that the 50-year-old supporter of Turkish President Recep Tayyip Erdogan was one of the goons who savagely kicked her while she was curled up in a ball during the melee.

“Absolutely,” Usoyan told The Daily Caller (DC), after reviewing Yildirim’s Facebook page to see if he was one of the men who assaulted her.

Yildirim, the owner of a construction company in New Jersey, was one of the most visible figures spotted in videos recorded of last week’s attack.

Completely bald and wearing a white shirt, Yildirim joined dozens of other Turkish men in a full-frontal assault on a group of peaceful protesters gathered outside the embassy.

In one video, Yildirim and other men were seen kicking Usoyan as she lay curled up on the sidewalk.

The video shows that after several kicks, Yildirim turned to assaulting Seyid Reza Dersimi, a Kurdish man who was attempting to protect Usoyan.

Dersimi also confirmed Yildirim’s involvement during a phone interview.

The DC was able to reach Yildirim at a phone number listed for his construction company.

“I don’t know what you’re talking about,” he said when asked about his involvement in last week’s violence. He ended the phone call after being asked for comment.

Given that Yildirim is not an official diplomatic agent for Turkey, and therefore not protected by international diplomatic agreements, it is unclear why he was not apprehended last Tuesday, or why he has not been arrested since, noted DC.

The Facebook page for Yildirim includes videos recorded in Washington, D.C. last week.

Ayhan Ozmekik, the president of the Turkish & American Youth Education Foundation and executive director of the U.S.-based non-profit group, the Turkish Institute for Progress, posted a photo on his Facebook page with a group of men, including Yildirim and several others involved in last week’s attack.

Also in the photo posted by Ozmekik is Mustafa Tuncer, a Turkish-American businessman who until last week was an executive with a group called the Turkish American Steering Committee (TASC), which was  identified in an internal State Department memo as having some sort of involvement in last week’s event.

That memo stated that the State Department found that some of the men involved in the attack were protected under diplomatic immunity. Others had been hired from within the Turkish-American community.

To note, however, Tuncer announced late last week that he was leaving TASC in order to spend more time with family. But he is the executive director for another group supported by Yildirim.

A Facebook post from April 2014 shows that Yildirim attended an event hosted by MUSIAD USA, a U.S.-Turkey trade group. Tuncer is executive director of the group.
