BALTIMORE (AP) - Prince took the stage in Baltimore before thousands of fans who were dressed in gray in tribute to a man whose death in police custody prompted riots and drew international attention.
The pop star announced Sunday's "Rally 4 Peace" concert at the Royal Farms Arena Baltimore after weeks of protests sparked by Freddie Gray's death. During the show, Prince debuted a song he wrote for the city after Gray's death.
"For those who have lost loved ones, we're here for you tonight," Prince told the crowd before launching a set that included his most famous hits.
Prince also called on the city's youth to fix a "broken system."
Baltimore State's Attorney Marilyn Mosby, who charged six officers in Gray's death, was invited to the stage and waved to the crowd.
