Minaj crew member stabbed to death
A member of Nicki Minaj's tour crew has been stabbed to death in Philadelphia, the singer has said.
Another crew member was injured in the attack.
Minaj wrote on Twitter that the pair had flown into Philadelphia for rehearsals two days ago.
Philadelphia police said two men, aged 29 and 26, were stabbed outside a bar early today.
They said the 29-year-old was killed and the younger man critically wounded.
Minaj posted a link to a TV report on the bar stabbings.
Police said a man started arguing with the victims inside the bar at about 2am local time and pulled a knife once they got outside.
Minaj said the stabbings are "another senseless act of violence that took the life of a great guy".
Police are offering a 20,000 US dollar (£13,000) reward for information leading to an arrest.
