Police and witness accounts agree that one officer responded and pursueda suspect to 55 Hilda St.

Witnesses described the arrest as a violent altercation involving Abdi and two Ottawa police officers; the one who initially pursued him, and a second officer who arrived at the scene.

Ottawa police Chief Charles Bordeleau has said paramedics were called 23 seconds after Abdi's collapse.

Audio from the paramedic dispatch shows that the first call for a paramedic vehicle came at 9:52:06 a.m.

The female dispatcher referred to the call as a Code 4 the highest priority, meaning ambulances should travel with lights and sirens and said "10-2s on scene," a reference to police.

The dispatcher said police were on scene "with a male unknown age, pepper-sprayed, bleeding from the mouth, unconscious."

Seven minutes later, at 9:59:10 a.m., a paramedic at 55 Hilda St. called to request backup.

"Patient is VSA [vital signs absent], we need another unit for backup please," the paramedic said.

At 10:01:24 a.m. the dispatcher dispatches a second vehicle to the scene, and repeats the details: that the patient was vital signs absent, bleeding from the mouth and hadbeen pepper-sprayed.

Five minutes later the dispatcher takes a call from an unknown man, who asks if there is any update from 55 Hilda St. She says paramedics are reporting a patient with vital signs absent and will know more soon.

Witnesses and video of the aftermath of the arrest show that when the first paramedic arrived at the scene he began CPR on Abdi with the aid of Montsion.

Abdi was taken to hospital in critical condition.
