"Sharkeisha" became the No. 1 trending topic on Twitter in the U.S. on Wednesday, after video of a young woman sucker-punching another woman in the middle of an argument went viral on Instagram and other social media sites.

And there may be a new twist in the case of the hard-fisted fighter, as unconfirmed reports alleging that the assailant has been arrested and supposed mugshots of the woman the world has come to know as "Sharkeisha" are swirling online.

There are not many concrete details about her possible arrest, but a number of Twitter users have uploaded photos of a woman who appears to resemble the one who instigated the one-sided fight in the popular video, and who has a name very similar to hers.

An iPhone screen-capture of one such mugshot, tweeted Wednesday morning by @desusnice, depicts a woman in a camoflauge-style shirt, and is tagged with the name "Sharkiesha Tyeshia Thompson," which may or may not be the name of the puncher in the video. It is not clear what the woman in question has been arrested for, or even if she is the same person seen in the infamous fight video. Here's @desusnice's photo:

Tagged "Ya'll can rest easy knowing Sharkeisha is in custody," the photograph had been retweeted nearly 300 times by early Wednesday afternoon.

But if online criminal record sites are to believed, this is not the first time "Sharkeisha" has been arrested, as multiple record search databases have published a mugshot of a "Sharkeisha Tyesha Thompson" of Charlotte, N.C., who closely resembles the girl in the above photograph. The records database NorthCarolina.arrests.org and other sites report that the photo of a woman in a red V-neck shirt was taken on Aug. 13, 2011, when Thompson was allegedly arrested on one charge of "uttering a forged instrument" and subsequently released on $500 bond. The sites describe Thompson as 20 years old, 5-foot-3 and weighing 190 pounds at the time of that previous alleged arrest, citing data collected by the Charlotte-Mecklenburg Police Department in North Carolina.
