After he was sent home Wednesday from his job at a private security firm at Little League Headquarters, Isaiah Randall texted his supervisor, telling him “You guys better have heavy security after the (expletive) you pulled today, because I will be back,” according to a South Williamsport police affidavit.

Police first learned of the threatening text message about 2 a.m. Tuesday, the court document stated.

Randall, 20, of 690 Sixth Ave., Williamsport, allegedly sent the text to Donald Bollinger, his supervisor at Securitas, a private security firm for whom he worked, police said. The company provides security for the World Series ESPN crew, police said.

Some time after sending the text, Randall posted on his Facebook page “‘Mass Casualty Event’ with a countdown timer under it that read: 01 day, 22 hours and 41 minutes,” it was alleged in the affidavit.

Randall then tagged ESPN, Little League and Securitas so that each one received the post, police said.

Neither police nor the affidavit stated what Randall actually did as an employee for Securitas.

It was unclear when Randall actually sent the threatening text to his supervisor. Police said it was sent “after Randall was sent home for (committing) a company policy violation.”

A warrant for Randall’s arrest was filed about noon Tuesday at the office of District Judge William Solomon, charging him with four counts each of terroristic threats with the intention to terrorize another, terroristic threats causing serious public inconvenience and harassment.

Randall’s alleged statement and post “caused Little League World Series, a place of assembly, to divert from normal operations,” Cpl. Trent Dunlap wrote in the criminal complaint.

“Given the nature of this international event, we believe a serious and undeniable threat was made by Isaiah Randall towards Little League International, ESPN, Securitas and all those attending this event,” the officer said in the document.

Members of the U.S. Marshals Fugitive Task Force went to Randall’s city home and took him into custody without incident. He was turned over to borough police who brought him before Solomon about 1:15 p.m. Following his arraignment on the eight felony terroristic threats charges plus the harassment counts, Randall was committed to the Lycoming County Prison in lieu of $125,000 bail.
