AKIPRESS.COM - A Baltimore grand jury has charged all six police officers accused in the death of Freddie Gray.

State Prosecutor Marilyn Mosby announced the revised charges on Thursday, but the most serious charges - including second-degree murder - remained, reports BBC.

Gray suffered a severe spinal cord injury in police custody in April and died a week later. His death sparked weeks of protests and later riots and looting in Baltimore.

"As is often the case, during an ongoing investigation, charges can and should be revised based upon the evidence," Ms Mosby said.

The grand jury did not return charges on the false imprisonment charges that were brought against some of the officers.

Ms Mosby brought the false imprisonment charges earlier claiming that Gray's arrest was unjustified and illegal.

However, the grand jury did return new reckless endangerment charges that were not part of the original charges announced three weeks ago.

Ms Mosby has said that Gray's neck was broken while he was being handcuffed and placed into a police van. She also said that police repeatedly ignored his pleas for medical attention.

The officers are scheduled to appear in court on 2 July.
