Police are hunting three teenagers after a seven-year-old boy was attacked and racially abused.
The child, who is from eastern Europe, was in Grimsby's Grant Thorold Park on Durban Road with his family.
Police say he was elbowed in the face and spat on by three teenage boys aged 16 to 18 years old.
A Humberside police spokesperson said: "The boy suffered a bruise to his forehead. It’s thought racially abusive terms were also said to the 7-year-old.
"The teenagers were wearing dark clothing and were all riding bikes. Two were on black bicycles and the third was on an orange one."
The attack happened near the children’s play area around 5.30pm on Sunday 23 June. Police are appealing for witnesses.
