David Mueller, a former Denver radio host, groped singer Taylor Swift backstage during a meet-and-greet at the singer’s concert in June 2013, Swift’s attorney wrote in a counterclaim Wednesday, according to reports. Mueller sued Swift in September saying that he was wrongly accused by Swift’s security team member of groping during a photo session and was fired two days later from his job at KYGO radio.

Mueller maintained his innocence in the incident, which allegedly happened at the Pepsi Center in Denver. According to Swift's counterclaim, Mueller claimed that it was one of his seniors at the radio station who groped the 25-year-old, the Associate Press (AP) reported. However, Swift accused only Mueller for the act, according to AP.

"Mueller's newfound claim that he is the 'wrong guy' and, therefore, his termination from KYGO was unjustified, is specious," Swift's attorneys reportedly wrote in the counterclaim. "Ms. Swift knows exactly who committed the assault -- it was Mueller."

Swift asked for a jury trial and said the compensation she might receive will be donated to organizations "dedicated to protecting women from similar acts of sexual assault and personal disregard."

Swift’s lawyers said in the counter argument that the singer was "surprised, upset, offended, and alarmed" when Mueller groped her. According to them, Mueller did not just brush his hand against Swift while posing for a picture, but lifted up her skirt, the AP reported, citing the court documents.

After Mueller was removed from his job, Swift's publicist reportedly issued a statement saying Mueller’s employer was provided with evidence after the alleged incident, following which it made its call to fire him.
