Reward offered after threat found at Walled Lake Northern High School

WALLED LAKE, Mich. – A $1,000 reward is being offered for information on a threat that was found Thursday at Walled Lake High School.

In a letter to parents and the school community, principal Greg Diamond said the "non-specific" threat was found in a girl's bathroom. The school was briefly evacuated while the Oakland County Sheriff's Department swept the school.

"We believe it to be non-credible at this point," Diamond said. "We will prosecute to the full extent of the law, when the individual has been identified."

The tip line is 248-956-4995.

"It is important for students to feel empowered to effect positive change so please encourage your student to share any relevant information in regard to this matter," Diamond said.
