A statement Wednesday from the South African Police Service said the robbery of Tutu's home in Cape Town happened between 7 p.m. and 9 p.m. Tuesday. That was the day the Nobel Peace Prize laureate and foe of apartheid spoke at the memorial service at a soccer stadium in Soweto township of Johannesburg.
The statement said: "At this stage, we cannot give further details, as the investigation into the matter is still ongoing. No arrests have been made as yet."
The 82-year-old Tutu had his home robbed in August as he and his wife slept inside. Both were unhurt.
Burglaries and home-invasions frequently occur in South Africa.
