The Students tactician failed to appear at the Randburg Magistrates' Court to answer claims of abuse and violence directed at his ex-common law wife Nicole Henderson and her new boyfriend Deon van Rensburg.
De Sa had reportedly told his children to warn their mother he had a baseball bat and a gun in his car, and that he intended to use them on Van Rensburg.
The courts had already issued a protection order last month, which has barred De Sa from entering her place of residence and from calling or contacting her by SMS, e-mail or by any other means.
Henderson's application to the court reads in part: "He tracks me down. I am not sure if I am being followed. He is mentally abusing me with ugly words.
"If he knows we are together, it goes on through the night. He is threatening to beat up my boyfriend. He told my kids he has a baseball bat and gun in his car. He has threatened to give me a hiding too.
"I don't think he is mentally stable at the moment and I am scared of what he might do. He is completely acting out of character, [he's] almost psychotic."
If De Sa does not oppose the application by Van Rensburg on 18 July, he faces more severe restrictions to leave the new couple alone.
Some of the SMSes Van Rensburg says he received from De Sa, which he attached on his application read: "Hey fat p***! Come visit and face me man to man. Coward!; [I] Always know where u r. U don't come to me. I will to u. F****d my family. U gonna pay. Hope u coming to Jhb! So we meet. Still running?; Next time I see u! U know. Be ready and be a man. If it takes 10 yrs. Its on. G Night Babe. XXX"
