A former coach in Montgomery County is facing stalking and harassment charges in an alleged revenge ploy.
Tim Udinski was a lacrosse coach at Lansdale Catholic High School.
The school fired him last fall after several heated arguments with players and staff.
Prosecutors also say he had been the target of unfounded accusations.
After that the Philadelphia Archdiocese received emails accusing the school's football and lacrosse coaches of soliciting sex from players but the allegations were unfounded.
Detectives say Udinski admitted to sending the emails.
He says he was mad about his firing.
