A man with a hammer who hit his helpless victim 10 times in 10 seconds before walking away laughing, has been jailed for nine years.
Kwakou Bekoe struck a 26-year-old man during the horrific unprovoked attack at a market in north London, captured on CCTV.
Police officers had made a 'dangerousness application' to the court which added a further two years to the original sentence of seven years.
A witness told police Bekoe, 32, laughed as he calmly walked away from the scene of the attack, which left the unnamed victim needing stitches to his head.
It happened on June 28, 2017 at about 4pm at Seven Sisters Indoor Market in north London.
The victim was stood at the rear entrance to the market with a group of associates when Bekoe entered with a separate group of people.
