Two Arlington County physical education teachers were charged with marijuana possession after police executed a search warrant at an elementary school campus last week, authorities said.

Michael Diaddigo, 28, and Luke Lloyd, 25, were suspended from Taylor Elementary School after police searched the school about 9 a.m. Friday, school and police officials said.

An anonymous tip had led police to the campus, police spokeswoman Ashley Savage said. A drug-sniffing dog found narcotics in the desks of Diaddigo and another teacher, according to the search warrant. Two unnamed informants told police that Diaddigo, Lloyd and a third gym teacher were "regularly using marijuana in the school building throughout the school day," the warrant read.

The teachers used marijuana in a windowless physical education office, according to the warrant, and used air freshener to mask the smell.

Both teachers were released on a summons. Diaddigo and Lloyd are scheduled for arraignments at 2 p.m. Wednesday in Arlington County General District Court, according to online court records. Diaddigo and Lloyd could not immediately be reached for comment Tuesday.

A third staff member was placed on leave pending a further police investigation, according to a letter Principal Harold Pellegreen sent to parents.

The principal told parents that the investigation is focused on the staff members and does not involve the teachers' interaction with students. "As educators, we are obviously shocked and dismayed by this news, and our first concern has been for our students," Pellegreen wrote.

Counselors were expected to visit classes this week to share information about the incident, the principal said.

"This is a disheartening situation for Taylor," Pellegreen said in the letter. "Please be assured that we will continue to work together to ensure that Taylor's students, families and staff are supported during this transition."
