Two teenage girls have been arrested after allegedly throwing stones and shouting racial abuse at a Slovakian man in Medway.
Police said community support officers would remain on duty
The incident is the third reported to Kent Police after reports of racially-motivated crime near a school.
It follows tensions between parents at Luton Junior School, involving the existing community and newly-arrived Slovakian migrants.
This week, talks were held between the police and community leaders.
Medway Council also moved to reassure parents, after a child was taken out of school amid claims of bullying, saying the school is a "safe place".
The latest arrests of two teenage girls, aged 16 and 18, who were bailed pending further inquiries, follow an alleged incident on Saturday, police said.
Police said the Slovakian man involved was not injured.
A woman, 35, has also been arrested and bailed after an alleged assault on a 10-year-old boy.
Another boy has been reprimanded by police after a report of common assault on a 36-year-old woman on 14 September.
Ch Insp Peter Wedlake has said police community support officers will remain on duty outside the school and racially-motivated offences will not be tolerated.
On Wednesday, Medway's director of children's services Rose Collinson said the school was a "safe place" for children.
She said: "Children in Luton Junior - children in Medway schools - are safe. They're learning. They're making good progress. They're playing well together.
"Children are safest in school - that's a good place to be. It's a calm place to be. It's a safe place to be."
