The man has been strongly criticised for seizing the towel on social media, while the fan who lost out has received sympathetic messages from fans.
The comments were posted to her 200,000 Twitter followers after a video emerged showing the scrap as the towel was thrown towards the youth at the end of Jack Sock's first round match at this year's championships.
To make matters worse, the tug-of-war unfolded on live TV, grabbing the attention of tennis fans across the globe.
The unknown souvenir snatcher has been called out on Twitter, most notably by Andy Murray's mum, Judy.
He tweeted: "If anyone knows the kid that unfortunately had the towel ripped out of his hands.tweet his name at me and I'll be sure to get him one".
The towel in question is popular due to players using them throughout the tournament.
The towels retail at £30 in the Wimbledon shops and the incident left Sock incensed.
A nice touch from the American! Sock is a title holder here in the doubles, winning the title in 2014 with Canadian Vasek Pospisil.
Sock will face Austria's Sebastian Ofner in the second round on Thursday.
