NORTH LITTLE ROCK, Ark. (KTHV) – Police in North Little Rock are reportedly investigating threats allegedly made by students on social media.

On Tuesday, Darlene Holmes with North Little Rock School District said three Lakewood Middle School students were removed from school for making threats on social media.

A school resource officer at Lakewood Middle School is said to have been called in to conduct an investigation of an alleged social media threat against staff and students.

"She said she was going to spare a few people and the few people were the ones that were tagged," said 8th grade student William Jennings. "My friend who got suspended, I knew he would never do anything like that but I don't know about the other two girls. We were all very wary."

The investigation is now being handled by North Little Rock police.

LITTLE ROCK, Ark. (KTHV) -- Just this year there have been 13 deaths attributed to high school football concussions. Now schools around the nation and locally are taking extra precautions to prevent these injuries, and one of them is North Little Rock.

Following THV11's extensive helmet investigation earlier this year North Little Rock spent $16,000 upgrading their helmets and concussion procedures.

"[The new helmets] help with confidence because I don't really have to focus on [safety] because I'm just playing my game," said running back D.J. Brown.

"I'm doing probably five more concussion assessments than I would prior to this device," added trainer Chad Williams.

The Charging Wildcats have been sporting new helmets- 30 of them with five sensors each to guage collision impact.
