A 16-year-old Buhach Colony High School student was arrested Wednesday night on suspicion of sending text messages threatening to kill students at the school, according to the Atwater Police Department.
The student wasn't identified by police. He is being held at the Merced County Juvenile Detention Center.
Neither parents nor students at the school had been told of the arrest as of Friday morning, said George Sziraki, a Merced Union High School District assistant superintendent.
At 7:30 p.m. Wednesday, a mother of a female Buhach Colony student contacted the Atwater police. She explained that she had found disturbing text messages on her daughter's phone, said Frank Pietro, assistant chief of the Atwater department.
"You guys better watch out, I can kill you," was the gist of the text message, Pietro said.
After Atwater police interviewed the girl, it was discovered that another student had received a similar text message.
That night, Atwater Police Department's school resource officer tracked down the 16-year-old at his home and, after an interview, arrested him, Pietro said.
By Thursday, the school's internal investigation found there was no imminent threat to students. Sziraki said the student who was arrested could be forced to go to counseling, be suspended or even expelled.
