A National Socialist leader has posted shocking footage of his violent attack on a Channel Nine security guard hours before the network was due to air a report about his extremist far-right group. National Socialist Network leader Thomas Sewell and his lackey filmed themselves arriving at the TV station's office in Melbourne hoping to confront A Current Affair staff ahead of the segment running on Monday night. Their request was denied and Sewell unleashes into an extraordinary tirade on camera slamming the staff as cowards and manipulative before a security guard emerges and orders the pair to leave. 'Sorry, you cannot film in the building,' the security guard, who is black, tells the man filming, who refuses to comply with instructions.The encounter quickly escalates into violence as he orders the guard to not 'f**king touch me' before Sewell unleashes a brutal attack on the security guard. https://www.dailymail.co.uk/news/article-9312631/Neo-Nazi-leader-films-bashing-Channel-Nine-security-guard-report-extremist-group.html
