SOMERVILLE - A teacher from Immaculata High School in Somerville is facing some disturbing allegations.

Patrick Lott, 54, a volunteer coach and high-ranking school administrator, is accused of using a hidden camera to spy on boys in the shower.

Authorities say more than a dozen boys were recorded, many of them under the age of 16.

Lott is being held on $500,000 bail. The now-former volunteer coach is facing dozens of counts, including second, third and fourth-degree endangering the welfare of a child and invasion of privacy.

Lott's attorney declined comment until he knows more about the charges against his client. Lott was an assistant principal at Bernardsville Middle School and prior to that, at the high school.
