A child being pushed in a pram was struck by an egg thrown from a passing car in Banbridge on Monday evening.
The incident, which happened on the Castlewellan Road area of the town shortly before 9pm, is being investigated by police as assault.
The child’s mother, SarahJane Purdy McLarty, posting on social media spoke of her sheer horror at the incident.
She explained: “Myself and my partner were out walking with our son when a speeding white BMW decided it would be hilarious to throw eggs out the window at us and hit our son.
“A woman passing us stopped to check our son was OK and told us she was also getting eggs thrown at her by the same car. What the actual hell is wrong with people.”
She later thanked everyone for their support, adding that her son, who has autism, is “okay” and “that’s all that matters”.
She added: “My son is autistic and isn’t able to tell us if he’s in pain so just gotta keep an eye on him.”
A police spokesperson said: “The egg struck a young child, and as a result, the report is being investigated as an assault.
“Enquiries are ongoing, and police would appeal to anyone who was in the area at the time, and may have any information which might assist, to contact officers on 101 and quote reference number 2216 of 22/05/23.
