( CNN ) A lot of questions . Not too many answers . Exactly one week after being taken into police custody in Baltimore , Freddie Gray died Sunday under circumstances that are unclear . `` The questions that many of you have are the same questions that we 're asking : How was Mr. Gray injured ? Were our proper protocols and procedures actually followed ? What are the next steps to take from here ? '' said Baltimore Mayor Stephanie Rawlings-Blake . An attorney for Gray 's family alleges that police are involved in a cover-up . `` On last Sunday morning at about 8 a.m. , the police chased Freddie Gray , a ... healthy man , without any evidence he had committed a crime . His take-down and arrest without probable cause occurred under a police video camera , which taped everything including the police dragging and throwing Freddy into a police vehicle while he screamed in pain , '' attorney William Murphy Jr. said in a statement . Video recorded at the scene shows Gray , with his hands behind his back , screaming as police raise him to his feet . They drag him to a waiting van . `` He lapsed into a coma , died , was resuscitated , stayed in a coma and on Monday , underwent extensive surgery at Shock Trauma to save his life . He clung to life for seven days and died today at approximately 7 a.m. We believe the police are keeping the circumstances of Freddie 's death secret until they develop a version of events that will absolve them of all responsibility , '' said Murphy . The attorney added that Gray 's spinal cord was severely injured . At this point , police are declining to say much about the case , citing ongoing administrative and criminal investigations . They have not released the incident report , nor have they released the names of the officers involved . They have said that those officers have been placed on administrative duties . When asked why officers first encountered Gray , Baltimore Police Dept . Capt . Eric Kowalczyk told CNN that they had been working in an area known for violent crime and drug sales . When the officers approached him , Gray fled , Kowalczyk said . Gray 's death comes amid a string of recent deaths involving white officers and black suspects . The death of Michael Brown in Ferguson , Missouri , touched off protests and sparked a nationwide debate over race and policing . Brown , an unarmed black teen , was shot by Darren Wilson , a white officer , last August . According to CNN affiliate WJZ , protesters rallied over the weekend in Baltimore , demanding answers . `` Our hope and goal here is to be as informative as we can without compromising the criminal investigation , '' said Kowalczyk . `` We 're very troubled by this . We want to find out the answers as much as the public does . '' CNN 's Vivan Kuo and Janet DiGiacomo contributed to this report .
