Halifax Regional Police arrested two people Thursday in connection with the early morning stabbing death of a man in Dartmouth, N.S.

Bradley Wayne Knoll, 59, died on Portland Street after being stabbed at around 2:14 a.m., said police.

Halifax police arrested a man in Halifax and a woman in Dartmouth on Thursday afternoon. No charges have been laid.

A man who saw a stabbing victim die said the incident was "very jarring."

Police were called to a fight outside 88 Portland St. and found Knoll, who was pronounced dead at the scene.

Jamie Clark lives in a downtown apartment near the scene.

"I woke up to the sound of a scuffle outside on Portland Street and ... clearly something violent was happening but I wasn't quite awake yet and in just a few seconds I heard a man started to yell, '911, call 911,' and he sound pretty exasperated," Clark told CBC News.

"He was clearly failing at that point. He was yelling 'Fire, fire' — clearly doing anything to grab attention."

Clark called 911 and went outside to see what was happening.

"I heard running down the street just after he started hollering and screaming, '911,' and then I went outside and waited for the police to come," he said.

"A car pulled around and [someone] went up to the victim and started doing compressions right away. It was pretty crazy, he was obviously in pretty severe distress. And then within a few minutes ... the [police] were there and they declared him dead, threw a sheet over him.

"It was very jarring. I'm probably going to move out of this neighbourhood now."

One block of Portland Street, between King Street and Wentworth Street, and the surrounding area were closed on Thursday morning but have since reopened to traffic.
