WATERBURY, Conn. (CBSNewYork) — A former Waterbury parks department worker is accused of poisoning his boss’s breakfast.

William Lampron, 43, of Naugatuck, laced his boss’ oatmeal in October with Speedy Dry — a chemical used to soak up liquids on roadways — after the two argued over his job performance, police said.

The supervisor developed severe stomach problems after eating the poisoned oatmeal, but has since recovered, police said.

Speedy Dry can cause extreme intestinal distress when ingested and one of the ingredients is a carcinogen, police said.

When interviewed by detectives, Lampron admitted to placing the chemical in the oatmeal because he was angry with his boss, police said.

Lampron was arrested Wednesday and charged with felony assault and reckless endangerment.

He was released on $5,000 bond and is due in court Dec. 13.

Lampron was placed on administrative leave after the incident, but resigned shortly before his arrest, police said.
