(CNN) The city of New York has agreed to a $3.3 million settlement with the family of Kalief Browder, who spent three years at Rikers Island prison without being convicted of a crime and killed himself in 2015.

Browder was a 16-year-old sophomore when he was accused of stealing a backpack and arrested, later charged with second-degree robbery. He was released in 2013 when the charges against him were dropped.

Browder had just turned 22 when he hanged himself in 2015.

The New York City Law Department confirmed the settlement of the family's civil suit.

"The family believes the settlement is fair and reasonable," Browder family attorney Sanford Rubenstein said at a news conference Friday. "But they hope that his memory will be honored with the reforms that still have to take place within our prison system."
