School was temporarily on lockdown, officials said.
MAPLEWOOD -- A ninth grade student was taken into custody Wednesday after police say he made an online threat to his high school that caused its students and staff to go on lockdown, police confirmed.
According to a statement from Maplewood Police Capt. Dawn Williams, the school was locked down shortly before 8 a.m., when Columbia High School officials alerted police to a threat made to the school via social media.
After an investigation into the threat, a 14-year-old student was arrested at his home in South Orange, Williams said. He was charged and released to a parent, police said. The exact charges were not immediately released.

A school spokeswoman did not immediately respond to a request for comment on the incident.
Police said they are continuing to investigate the incident.
