A 47-year-old homeless man, upset about the lack of cheese on a turkey sandwich, attacked a pair of nurses Monday morning at Lehigh Valley Hospital-Muhlenberg, police allege.

Robert Vangorden

, no known address, was at the hospital at 5:36 a.m. for a psychological evaluation, according to Bethlehem police Lt. Mark DiLuzio. Vangorden accused nurse Ralph Pester of lying to him and punched Pester in the chest, DiLuzio said.

Later Monday morning, Vangorden was given a turkey sandwich at the hospital, but became enraged when he discovered that his sandwich lacked cheese, police said.

Vangorden stormed out of his room, according to a police report, yelled about not having cheese on his sandwich and was confronted by nurse Loriann Meyer, who told him that they didn't have any cheese for him. Vangorden allegedly threw the sandwich on the floor and told Meyer to eat it, then he tried to hit her twice, but Meyer deflected the blows. He also allegedly spit on a doctor.

Security restrained Vangorden and called police. He was charged with aggravated assault, simple assault, harassment and disorderly conduct.

Bethlehem police have had frequent run-ins with Vangorden, according to DiLuzio, and a review of court records in Northampton County shows he has been charged with public drunkenness, and other minor offenses, at least seven times in the past two years.
