Det Insp Shaun Inkpen說。"我們正在進行一些調查，以確定事件的全部情況，該事件使一名男子頭部受到非常嚴重的傷害。
A man is in hospital with life-threatening head injuries after he was assaulted and knocked unconscious.
Dorset Police said the 67-year-old was attacked by a man in Christchurch Road, Bournemouth, on Thursday at 21:52 BST.
His attacker also assaulted another man, leaving him with cuts and bruising, and pushed a woman to the ground when she tried to intervene.
The man then stole an electric scooter and made off towards the Pokesdown area.
No arrests have yet been made. The suspect is described as white, of large build, with short dark hair, and was wearing a grey tracksuit.
Det Insp Shaun Inkpen said: "We are making a number of enquiries to establish the full circumstances of the incident, which has left a man with very serious head injuries.
"I am particularly keen to speak to the woman who tried to intervene, to establish whether she sustained any injuries, and the man who had the electric scooter taken from him."
