Four-time Grand Slam champion Naomi Osaka hit back at a fan on social media that she says called her a "fluke" just a day after she was forced to retire from a match at the China Open due to a lower back injury. 

Osaka, who returned to the sport this year after an 18-month hiatus during which she gave birth to her daughter Shai, posted a rant on Instagram calling out the internet troll by reminding them of her decorated resume. 

"I just saw someone call me a fluke. How is it possible to be a fluke with 4 Grand Slams, lighting the Olympic torch, beating multiple top 20 opponents and being close to top 50 the year after giving birth?"

She continued, "FOH, you couldn’t even touch one of my accomplishments with your fingernail." 

In the post shared to her Instagram Stories, Osaka added, "Did I lieeeee????" 

Osaka, 26, won her first career Grand Slam in 2018 when she defeated Serena Williams at the U.S. Open, dropping just one set the entire tournament. She would win in New York again in 2020 and win two more major titles at the Australian Open in 2019 and 2021.

But Osaka’s return this year hasn’t been without its struggles. 

She lost in the first round of the Australian Open in January and exited the French Open and Wimbledon after the second round. Her performance at the 2024 Paris Olympics wasn’t much better, with a first-round loss to Germany's Angelique Kerber. 

Following a second round loss at the U.S. Open, Osaka announced that she would be parting ways with Wim Fissette, who coached her to two of her Grand Slam titles. 

She picked up her first win with new coach Patrick Mouratoglou at the China Open last week, but was forced to retire from her Round of 16 match against Coco Gauff on Tuesday due to a lower back injury.

New search warrants reveal the men accused of killing 12-year-old Jocelyn Nungaray are possibly members of the Venezuelan gang Tren de Aragua. 

Franklin Pena, 26, and Johan Martinez-Rangel, 22, were indicted last month on capital murder charges in connection with Nungaray's murder. 

Documents say Pena and Rangel kidnapped the 12-year-old and caused her death by applying pressure to her neck. The two are also accused of sexually assaulting her before leaving her body under a bridge. 

The new search warrants regarding the alleged gang involvement were filed in the District Court of Harris County and obtained by FOX 26 Houston.

The men's alleged association with the gang, also known as TdA, was discovered after searching their social media accounts. 

The TikTok account believed to be linked to Rangel had used ninja, crossed swords and classical building emojis, which are known to be associated with the gang. TikTok did not immediately respond to a Fox News Digital request for comment regarding the new search warrants.

Investigators also observed a video of Rangel "wearing Jordans and Gucci," brands also connected with the gang. 

Pena's TikTok account had photos showing tattoos known to be associated with the TdA gang, which included one star on each shoulder and a rose tattoo on his hand. He was observed on video wearing Air Jordan brand and Chicago Bulls brand clothing, the search warrant says.

"I believe that Johan Jose Martinez Rangel and Franklin Jose Pena Ramos utilized multiple social media applications and accounts to communicate with gang members about gang activities," one of the investigators wrote in a search warrant. 

The search warrant requests further data from the suspects' phones and social media accounts, in search of more evidence to tie the men to their alleged offense of capital murder.
