The decision came after six days of jury deliberations
The judge in Bill Cosby's sexual assault trial has declared a mistrial.
The decision by Judge Steven O’Neill came after six days of jury deliberations, the New York Times reports.
Despite long hours of deliberation, jurors told the judge they were not able to reach a unanimous verdict on charges against the sitcom star.
Prosecutor Kevin Steele announced in court that he will re-try Mr Cosby, according to The Washington Post.
The case focused on claims made by Andrea Constand that Cosby drugged and molested her in his Philadelphia home in 2004.
Several witnesses were called to testify, including Kelly Johnson, who accused Cosby of sexually assaulting her in 1996.
Johnson is one of more than 60 women to have accused Cosby, with the allegations of sexual assault dating back decades.
Due to statute of limitations, Andrea Constand was the only accuser able to take a criminal case against the 79-year-old entertainer.
Speaking outside court yesterday, Mr Cosby said: "I want to thank the jury for their long days.
"I also want to thank these supporters who have been here - and, please, to the supporters, stay calm. Do not argue with people. Just keep up the great support. Thank you."
