An 18-year-old girl was arrested Thursday for a fake bomb threat at Victor High School, officials said.
Betsy Rodriguez, a senior, was charged with first-degree falsely reporting an incident and was sent to Ontario County Jail on $2,500 bail.
The high school's 1,700 students were evacuated after a threatening note was found around 8 a.m. in a girls bathroom, school spokeswoman Kara Conners said.
The note said a bomb would go off at 12:30 p.m. and another on Friday, Sheriff's Lt. Ronald O'Brien said. He said Rodriguez confessed there were no bombs.
Students returned to the building around 12:45 p.m.
Victor is 16 miles southeast of Rochester.
