A Lakewood man was arrested after he posted a threat on social media that he would open fire with a machine gun on a rally calling for stricter gun laws, authorities said.

Shane Steele, 42, was charged with one count of terroristic threats after he was arrested on Friday, Ocean County Prosecutor Joseph Coronato announced in a statement.

Authorities were alerted to the post on Facebook from a tip to the Manalapan Police Department from a concerned citizen, Coronato said.

"Steele allegedly authored a post on Facebook stating he intended to open fire with a machine gun at a 'March For Our Lives' rally," the statement said.
