Taking to Twitter on Wednesday afternoon the Hughesy & Kate co-host posted an image of her right arm, clearly showing a huge bruise.
Langbroek captioned: 'This is the bruise I sustained trying to keep that 'vulnerable' resident from kicking our front door in on Friday night. Children inside. The real vulnerable are the decent citizens of St Kilda.'
The comedian is claiming that she and her husband had arrived back in St Kilda when a man attempted to force his way into her babysitter's car, before being involved in an altercation and trying to break into their home.
As she went to investigate, the 'deranged' man turned on Langbroek and attempted to push past her and into where her children, aged from eight to 12, were sleeping.
The radio personality has called on the Victorian government to 'clean up' the area which has a long history of drug overdoses, homelessness and street sex workers.
The man responsible for the attack has reportedly been charged by police.
