Freddie Gray Ask For Inhaler Inside Police Van Before Death

Dozens of protesters went marched through downtown Baltimore on Thursday hours after police said they had turned over their internal investigation to a prosecutor.

Police revealed their inquiry had uncovered a previously unknown stop by the van which took Mr Gray to the station.

It was captured by a camera outside a small grocery store.

Shop owner Jung Hyun Hwang said his original recording of the CCTV was on a laptop that was stolen during the city's riots on Monday night, but police had been able to obtain a copy.

Before Mr Gray - who was allegedly found to be carrying a switchblade - was put in the van, he asked officers for an inhaler, but did not receive one.

At the first stop, he was put in leg cuffs because police said he became "irate".

The second stop, which has only just come to light, took place at the junction of N Fremont Avenue and Mosher Street.

The van stopped a third time, and the driver asked for an additional unit to check on Mr Gray.

At a fourth stop, the wagon picked up another prisoner.

The prosecutor, who must now decide whether to charge six police officers involved in the arrest, asked the public on Thursday to remain patient.

State's Attorney Marilyn Mosby, 35, is the youngest top prosecutor of any US city.
