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 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.”
