WASHINGTON — Rihanna had plans to be part of the healing of Baltimore after the April protests.

The music star wanted to play a free concert for the city, as well as walk with protesters.

But in newly released emails obtained by The Baltimore Sun, police might have stopped an attempt at holding a show.

“Possible Rihanna Concert at Penn & North,” the May 1 update reads. “No time given. Police are claiming they have no permit so it will not be allowed.”

The emails requested extra police security.

In the end, Prince played a show on May 10, performing a song about the unrest in the city brought about by the arrest and death of Freddie Gray.

On a related note, internal emails obtained by The Baltimore Sun show Mayor Stephanie Rawlings-Blake and Maryland Gov. Larry Hogan disagreed about how to deal with the April riots.

Rawlings-Blake wanted to lift the curfew, which barred people from being on city streets between 10 p.m. and 5 a.m., on Saturday, May 2, but Hogan disagreed.

Hogan’s spokesman said the curfew was curbing violence and it shouldn’t be lifted. It was lifted on May 3.

Officers charged in connection with Gray’s death have pleaded not guilty.
