Cape Town, Dec 4 (DPA) Part of Cape Town International Convention Centre, venue for the World Cup final draw, was sealed off Friday following a bomb scare.

The alert, hours before the draw takes place, followed an earlier bomb scare at Cape Town airport, police said.

The media entrance to the convention centre was sealed off shortly after noon. A police squad was combing the entrance for explosive devices with sniffer dogs.

'It's just a bomb threat. It's not the first one. We had one this morning at the airport,' police spokesman Vish Naidoo told the German Press Agency (DPA).

Naidoo, who was on his way to the convention centre to address the media, did not say how police were alerted to either threat.

Police arrested a man in a Cape Town suburb of Goodwood over the airport scare, he said.
