This thing is just insanely dangerous, as these people don't care who they hurt in the process to get what they want. That is why none of us are saying anything publicly," the well placed source, who has knowledge of Cape Town's underworld, said on Sunday.The source went on to confirm a Sunday Times report that a R1m hit was put out on Mihalik from jail."It is all true."The newspaper reported that two crime figures arranged with a Gugulethu tavern owner who was serving time in jail for armed robbery to have the lawyer killed.
