Hugh Huddy, RNIB campaigns officer, said: "Everybody has the right to feel safe while going about their daily lives whether that person has sight loss or not. If someone is specifically targeted because they're blind or partially sighted that is obviously appalling.
"When you lose your sight it can be extremely traumatic and often people can lose confidence so feeling safe in public places is vitally important in ensuring people with sight loss remain independent.
"RNIB would urge anyone who witnessed the incident to contact the police."
