[Highland Park] Too many unsupervised children just hanging out

I live on the Highland Park side of Heths Avenue. Saturday night my house was egged. When I returned home at 10 p.m., there were upwards of 30 unsupervised children from 8-12 in front of my home. I have talked to other neighbors, and we are all concerned about these unsupervised children that hang out on Heths Avenue between Wellesley and Hampton. This needs to be monitored by the police, and I have written to 311 and asked to have this issue addressed. Kate Snow
