Zurich - A group of 29 Ghanaian musicians disappeared after attending a youth music festival in Zurich, local police said on Monday.

Four women and 25 men were scheduled to return to Ghana last Wednesday, but they failed to show up to take their plane home, said Zurich police spokesperson Silvia Muelli.

A representative of Zurich's music festival accompanied 33 musicians to the check-in counter at the city's Kloten airport, but only three of them showed up at take off, Muelli said.

The remaining 29 disappeared and their whereabouts have not yet been established.

Police are searching for them as their actions contravene Swiss law, Muelli added.

The Ghanaians, who all held a valid passport, entered Switzerland with a collective visa on July 7.

The city of Zurich invited the group to attend its world youth music festival from July 8-12.

The story on the disappearance of the Ghanaian immigrants had dominated the front pages of leading newspapers as well as internet websites across Switzerland and the world as a whole.

The Ghana Embassy in Switzerland are engaged in an emergency meeting to find out means to address the issue in order to save the image of Ghana which could be dented by this development.
