A thug attacked a partially sighted man in a busy Brighton street during the evening rush hour.
Sussex Police have issued a CCTV image of a man they would like to speak to about the attack.
The force said: “The 51-year-old victim was passing Subway in Western Road at about 5pm on (Tuesday) 17 March when he accidentally collided with a man on the pavement.
“The men argued before the victim was elbowed in the head and kicked in the knee by the attacker.
“The attacker then walked away west along the road towards Hove.”
PC Marcus Clark said: “This was an unprovoked attack on a vulnerable man that seems to have started from nothing.
“Although this happened several weeks ago we are still determined to find the man involved.
“If you recognise the man in the CCTV or know where he could be, please contact us.”
Anyone with information is asked to phone Sussex Police on 101, email 101@sussex.pnn.police.uk or call the independent charity Crimestoppers anonymously on 0800 555111.
