It is alleged the teen tried to hire a prisoner to kill the 28-year-old man who was in custody at Kgosi Mampuru II Prison at the time. According to the State, the father allegedly assaulted the four-month-old baby so badly that he had a broken femur and ribs. The case against a teenage girl from Pretoria, who stands accused of conspiring to murder her former boyfriend after he allegedly assaulted their baby, has been postponed after her legal representative failed to appear in court.
