SINGAPORE - The last thing Mr Muhammad Safuan Mohamed Nasil, 23, remembers before blacking out on Dec 27 last year was going into an Orchard Road 7-11 outlet.
When he opened his eyes again, he found himself in hospital and was shocked to see the date, with the year 2013, written on a board.
He later found out he had been in a coma for about three weeks.
Court papers said he was at Cathay Cineleisure Orchard when he saw his friend being assaulted by a cleaner, Lukman Nurhakim M. Thamrin, 23, in an unprovoked attack.
When he went to his friend's aid, Lukman punched him. After he fell to the floor unconscious, Lukman slammed his motionless body on the floor.
District Judge Mathew Joseph called Lukman's assault one of the worst he has seen. He said he had viewed the closed-circuit television (CCTV) footage and that it had a chilling effect on the court.
On Friday, Lukman was sentenced to three years and nine months' jail, and six strokes of the cane.
He pleaded guilty on Sept 24 to one count of voluntarily causing grievous hurt and one count of voluntarily causing hurt.
Two other charges - for assault and housebreaking - were taken into consideration during sentencing.
Mr Muhammad Safuan is willing to forgive Lukman, but still does not understand why he had been attacked.
