Was walking from Manor lakes shopping centre towards Wyndham vale station. Then suddenly felt some one hit me hard on my left side of the head which I then fell down and my was bleeding. Then gathered my self and started walking but the magpie started following me in attempt to attack again and again. I placed my bag on my head and tried to walk at my pace. After waking 300 metres and 15 attempts from magpie attempt it somehow stopped and sat on one of the billboards watching me. I am really scared as this is my first time never new a bird can cuss such sort of damage. I will be going to doctors to get checked and informed at work if this incident. Please need some sort of issue reported so it does not happen to others.
