A year after the alleged attack on two gay men in Pennsylvania by a "clean cut" gang made national headlines, one of the men who was with the aggressors but not charged, filed a lawsuit against his former employer for firing him. He is alleging slander.

According to a report in Philly.com, Francis McGlinn, who was present during the September 11, 2014 attack on two gay men in Philadelphia, filed notice Friday that he will sue the Archdiocese of Philadelphia. Following the national news coverage of the attack last September, McGlinn, who was identified on surveillance video, was fired from his position as assistant basketball coach of Archbishop Wood High School in Warminster, Pa.

McGlinn, who has never denied being present during the altercation, was never criminally charged. According to Philly.com, some media reports said he tried to act as peacemaker that night.

As reported in July by EDGE, lawyers for Philip Williams, 24, Kathryn Knott, 24, and Kevin Harrigan, 26, were offered a plea deal with the Philadelphia District Attorney's office. All three suspects are being charged with conspiracy and two counts of aggravated assault, simple assault and recklessly endangering another person, for the attack on gay couple Zachary Hesse and Andrew Haught.

According to the prosecutors, the suspects used gay slurs towards Hesse and Haught and physically beat them. Haught was injured with multiple broken bones, having his jaw wired shut for two months. According to a spokesperson for the Philadelphia District Attorney's office, if they are convicted on all charges, the maximum sentence could be as high as 34 to 68 years in prison.

Williams, Knott and Harrigan are scheduled for a pre-trial hearing Thursday.
