A man who used a machete to end a bizarre but savage string of attacks in a downtown Edmonton neighbourhood last weekend believes he would be dead if not for his weapon.   

""No knife ... he'd of killed me," said Chandar Singh, 68. "Oh yeah ... 100 per cent."

Singh was asleep when he awoke to the sound of someone kicking in the back door of his McCauley home.

Minutes later a man came crashing through his bedroom window and landing on his bed.

The man demanded money and started punching him.

"He hit my chest here, other one of my eyes," he told CBC News.

Singh grabbed a machete that he kept in his room.

He managed to strike his attacker with it and ran from his bedroom to his living room.

The man gave chase and Singh swung again.

Finally the man, leaving a trail of blood from his head, face and arm fled through the front door. 

Police were already in the neighbourhood investigating two related random attacks on residents, one which left a man in hospital on life support.

Three men aged 21, 26 and 27 are charged with attempted murder.
