A teenage boy was left with concussion and in need of hospital treatment after being attacked in the town centre.
Harrison Brown, aged 13, was with his friends having a snowball fight when the assault happened last Monday (February 5), his furious mum Mikaela said.
She said: “Harrison and his friends were on their mountain bikes in the underground car park near The Source.
“The four boys were having a snowball fight with each other. But one snowball went astray and unfortunately hit a female passer-by, and my son was attacked from behind.
“A man charged at Harrison, rugby tackling him. He threw him off his bike and Harrison hit a brick wall.
“Harrison had to go to hospital as he had concussion and needed a steri-strip to close a wound he got above his left eye.
“His bike was damaged as well.”
Harrison’s mum added that her son was helped by staff at McDonalds in the town centre shortly after the attack last Monday evening.
She said: “I was at a parents’ evening at school and got a phone call to say Harrison had been hit by someone.”
It is believed that the suspect was with a group of people and aged between his late teens and early 20s.
