HAMILTON (Mercer) — The longtime baseball coach at Steinert High School was arrested this month on a simple assault charge.

Police told NJ.com they arrested Brian Giallella after a woman claimed he threw a lamp at her inside his Hamilton home on Nov. 8. The woman declined medical attention despite an injury to her face, according to the report.

Giallella, on his school website, said this year was his 20th as a math and computer science teacher at the high school which is one of three in Hamilton and is also known as Hamilton High School East.

Giallella wrote that he began his teaching career at Notre Dame High School in Lawrence in 1998.

The baseball field at Steinert is named after his father Rich Giallella, the school's former athletic director and baseball coach.

Hamilton Police and Hamilton superintendent Scott Rocco have not yet returned messages.
