Johannesburg – Wits University vice-chancellor Adam Habib had his cellphone stolen in Braamfontein on Thursday.“I was doing something that I have often advised my children, students and staff not to do,” he said in a statement on Friday.“I was walking to a meeting in Braamfontein yesterday afternoon, speaking on my cellphone. Someone ran past me, grabbed my cellphone, jumped into a car and sped away.”“The Braamfontein security guards were at my side within minutes, but they were on foot and the car sped off before they could give chase,” he said.Hillbrow police spokesperson, Sergeant Mdu Zondo said a case of common robbery was opened. No arrests had been made.He said he should have been more careful and urged others to be vigilant when using their phones outside the university. He said crime in South Africa was an “untenable situation”.“We have previously spoken to the police about crime in the area and increased private security patrols on the streets. We do however need a concerted effort from the police and all members of our community to keep our streets safe and crime free,” he said.Please be careful not to walk in Braam while on a phone. I stupidly did so and was mugged by a guy in red sweater who jumped into black car.— Adam Habib (@AdHabb) July 27, 2017Earlier in the year, Habib made a video about crime.
