The school did not detail the content or the type of communications but said the "proper authorities" had been notified, school president George E. Andrews Jr. wrote in the letter obtained by The Baltimore Sun.
"Our Mount Saint Joseph family has weathered a number of difficult days over the course of our 137-year history. Today is such a day," Andrews wrote in the letter.
"Our students mean everything to us. … As such, we have the highest expectations for our faculty and administrators. And when these standards are not met, we have a responsibility to our boys and their families to take action," the letter continued.
