A man who was assaulted while trying to intervene in a robbery attempt at the Southgate Centre earlier this week has died, according to a Facebook post from his wife.

Sharon Armstrong said on Facebook on Friday afternoon that her husband, Iain Armstrong, had died. 

Iain Armstrong suffered severe head trauma on Tuesday after stepping in when he saw a man try to steal from a vacant kiosk at the mall. It's unclear if a weapon was used in the attack.

"Tragically, due to catastrophic injury, Iain passed away today at about 3 p.m.," reads the Facebook post. "The entire family has felt covered in prayer throughout this ordeal, and sends their heartfelt thanks."

On Thursday, a Facebook post said the 61-year-old man was in a coma and had a spinal cord injury.

Attack was 'brief but vicious'

Edmonton police on scene earlier this week likened Armstrong to a "Good Samaritan" for intervening.

They had words of caution, as well.

"In the age we have right now, where everyone has a cellphone, we encourage people instead of being Good Samaritans by intervening in things like this, to try to get whatever is happening on video," Insp. Erik Johnson said. "Because it definitely helps the police investigation,"

He described the assault as brief but vicious. ​

Mall security footage has captured a clear image of the main suspect in the attack.

Police said earlier this week that two men have been arrested and interviewed.

The male suspect is still at large and police are not releasing any further descriptions of the suspect, according to a news release sent late Friday. 

Homicide detectives have now taken over the investigation and an autopsy is scheduled for Tuesday.
