BALTIMORE (WJZ) — A man arrested by Baltimore City police remains in a coma right now at a city hospital. Friends and family want to know how he wound up in critical condition.

Now investigators release a timeline of the events that led up to Freddie Gray’s hospitalization.

Meghan McCorkell has more on the case.

Investigators still haven’t said why they arrested Gray in the first place, as he spends a fifth day in critical condition.

Cell phone video shows Freddie Gray screaming as police drag him into a transport van Sunday morning. He was in a coma at Shock Trauma Monday.

“There’s a lot of questions. This is very serious, and we need to get to the bottom of this,” said Deputy Commissioner Jerry Rodriguez, Baltimore City Police Department.

Now police have released a timeline of the arrest. Investigators say they first encountered Gray at 8:39 a.m. at the corner of North and Mount streets, but he ran away.

At 8:40 a.m., they caught up with him and took him into custody in the 1700 block of Presbury. Two minutes later, officers called for a prisoner transport van.

At 8:54 a.m., Gray was put in additional restraints inside the van. Police say video surveillance shows he was conscious and talking.

But, at 9:24 a.m., an ambulance was called to the Western District police station to take him to the hospital.

Now friends and family members want to know what happened between 8:54 a.m. when the van left and 9:24 a.m. when Gray needed medical attention at the police station.

“It wasn’t right. And the time frame that they’re saying the time the ambulance came just don’t add up,” said Anthony Melvin, friend. “Where was he at and what was they doing at the time? That time should be accounted for.”

Neighbors say this has caused an uproar in the community and reinforced a distrust of the police.

“When they cross the law, they should be tried that same way we’re tried when we’re breaking the law. But the thing is, they’re not being,” said Darren Pack, West Baltimore.

Police leaders are vowing a thorough investigation.

All four officers involved in the arrest are now on administrative duties pending the results of the investigation.

A candle light vigil for Freddie Gray is planned for Saturday night in the 1700 block of Presbury. The group plans to march to the Western District police station.
