Hip-hop star Akon has been charged by police after a fan said she suffered concussion when he allegedly threw a teenager off stage, hitting her.
The incident occurred in June
The incident occurred in June at Dutchess Stadium in Fishkill, north of New York City.
The singer is scheduled to appear in court next week on charges of endangering the welfare of a minor and second-degree harassment.
Injured fan Abby Rosa said she had hired a lawyer over the incident.
Audience members at the concert told Associated Press a spectator lobbed something at the singer and Akon asked the crowd to point out the culprit.
A security guard picked out a 15-year-old and sent him up to the stage, where Akon is said to have picked him up onto his shoulders and threw him into the crowd.
Abby Rosa said the boy landed on her. She told a local newspaper she was later diagnosed with a concussion.
Akon's lawyer has said there is no basis for criminal charges.
The singer caused controversy in April when he danced provocatively with a teenage girl onstage in Trinidad.
He later apologised for the incident saying he did not know the girl was underage.
