He was also ordered to do 100 hours of unpaid work and was made the subject of an electronically monitored curfew for three months,
Judge Simon Phillips told Brown: "It was an unjustified, unlawful and violent attack.
"You punched him forcefully and repeatedly to the face and to the head.
"The CCTV footage, while not the best quality, shows that you are substantially more powerful and bigger."
