William McLeod, a fourth grader at Valley View Elementary School, received the ash marking -- made in the shape of a cross and applied by a priest --  for the Catholic religious day that signals the start of the Lenten season and then went to school in Bountiful, Fox 13 reported. He told Fox 13 he was the only student who had ashes.

"A lot of students asked me what it is. I said, 'I'm Catholic. It's the first day of Lent. It's Ash Wednesday,'" William said.

William's teacher, who was not identified, later approached him and forced him to wash off the symbol, he said. William reportedly attempted to explain why he wanted to keep the ash cross on his forehead, but he said his teacher wouldn't listen.

"She took me aside, and she said, 'You have to take it off,'" William said. "She gave me a disinfection wipe — whatever they are called — and she made me wipe it off."

William's grandmother, Karen Fisher, told Fox 13 she was "pretty upset" by the incident and received a call from the school's principal and the teacher who ordered the cross to be washed off.
