The bomb threat at Lakeland High School Monday morning was called in to 911 by an untraceable cell phone, said school officials.

“It was called in shortly after seven,” said Bethanne Bradshaw, spokeswoman for Suffolk Public Schools. The threat did not cause much of a delay, she said.

“The biggest pain was the traffic jam,” she said. The backup of buses and traffic onto Kenyon Road did cause a few problems, but the situation was cleared up by 8 a.m., Bradshaw said.

The fire department and bomb-sniffing dogs were brought out to the school, but detected nothing, she said. Bradshaw added that calling in a bomb threat is a crime, and that it costs taxpayers a lot of money.

“It tends to be somebody that wanted to get out of a test,” she said.
