Youngsters screamed when Saul Gentles, 31, and his brother Joseph, 33, drove up in a van, leapt out and targeted their victim, said Rhianydd Clement, prosecuting.
At one point, the younger brother got back into the van and reversed it towards the victim.
The Selby street was busy with young children and their parents on their way home from a nearby school.
The victim told police he wouldn’t give a statement against the brothers because he was scared of repercussions, said Ms Clement.
Two teaching assistants on their way home from work called police and the brothers were arrested.
Both school staff members told York Crown Court they had a duty because of their occupation to protect their school’s children inside and outside the school grounds but were so worried about possible repercussions for themselves of giving evidence against the brothers, they had been scared when walking around Selby afterwards.
One said their mental health was so affected they tried to retract their statement and had to be forced to attend the brothers’ trial through a witness summons.
