*Authorities in Norway detained R&B singer Ne-Yo on Saturday after a member of his entourage allegedly assaulted a restaurant worker.

The artist was reportedly partying at the Emil & Samuel restaurant/nightclub in Oslo following a performance in the city, when one of his associates allegedly punched a bus boy in the face as he walked past the group’s table.

Blogger Perez Hilton reports another member of the singer’s entourage then ran into the restaurant’s kitchen and allegedly threatened staff with a knife. The group subsequently left the venue, but was immediately detained and searched by police.

Officers are said to have released the group, but the restaurant bosses are reportedly planning to press charges over the incident.

The owner of Emil & Samuel said, “All in all this is an unfortunate situation involving the artist, Emil & Samuel and the concert management.”
