CRI听力:Protest in Baltimore against Death of Black Suspect in Custody

Thousands of protesters took to the streets of Baltimore on Saturday to demand answers to the death of Freddie Gray in police custody.

Demonstrators held signs with slogans such as "Jail Killer Police!" and "Stop Black Violence!".　

"Thank you, for standing up and never let the oppressors be the ones to have you sit down. And don't let them throw their ministers or whoever out here and try and take it away from what's real, because the only real thing is getting justice."

Freddie Gray was arrested on April 12 after he made eye contact with officers and ran away.

Officers held him down, handcuffed him and loaded him into a police transport van.

Human rights activist Graylan Hagler calls for actions to address the issue.

"What we need to talk about right now, right now, is basically how we begin to demilitarize the police department not only here, but across the country."　

Gray died on April 19 after suffering a fatal spinal injury while in custody.

Authorities have not explained how or when Gray's spine was injured.

Video showed him being dragged into a police van and police have said he rode in the van for about 30 minutes before paramedics were called.

Late on Friday, Deputy Commissioner Kevin Davis said Gray should have received medical attention at the spot where he was arrested - before he was put inside the van without a seat belt.

Police-related violence has ignited growing anger across the US over the past months.
