N-Dubz star Dapper was threatened by a man with a knife at a nightclub in Manchester at the weekend, it's been reported.

The rapper was said to be enjoying a night out with bandmates when a group of men approached him on the dancefloor at the Coliseum club.

An altercation is then understood to have taken place, during which a knife was drawn.

However, N-Dubz' personal security team were able to break up the incident, before safely escorting the band from the venue.

A source told The Sun newspaper: "A bloke waltzed straight up to Dappy and started going off in his face.

"It all happened so quickly. There was a huge fight. The main guy had a knife."

The source added: “It was very threatening.”

Last week, police confiscated paintball guns from N-Dubz after they were spotted firing pellets at fans.

The group were in Manchester as part of their UK tour, which is scheduled to continue tonight (April 12) in Reading.
