WILTON — The Police Department is investigating a case of criminal mischief to the old Primary School, arson of a Porta Potti and a man who fled after police stopped him for littering, Chief Dennis Brown said.

The School Street building, which the Board of Selectmen are seeking to sell, was spray painted with graffiti on the outside  last week. Damage is estimated at around $500. No damage was done to the inside of the building. Police are pursuing a person of interest.

This is the second recent criminal mischief complaint of that type, he said.

Neighbors to Bass Park reported a Porta Potti at the park on the Lake Road was engulfed in flames Oct. 4. Police and Wilton Fire Dept. responded to the scene. The estimated replacement cost is about $300.

Porta Potties in the park are rented by the town for the summer. This older-type model was to be picked up soon, Town Manager Rhonda Irish said.

A man who police observed littering on Route 2 near the Big Apple was stopped last week and then he fled on foot. An officer and his trained dog were called, but the man was not found. Police have identified a person of interest, Brown said.

Anyone with information about any of these incidents is asked to call the police department at 645-3876.
