FORT PIERCE, Fla. — About two months before Joseph Michael Schreiber allegedly tried to burn down a mosque sometimes attended by Orlando nightclub shooter Omar Mateen, he posted on Facebook that “All Islam is radical” and that all Muslims should be treated as terrorists and criminals.

Schreiber, 32, was arrested without incident Wednesday afternoon and was being interrogated by investigators looking into the fire set late Sunday at the Islamic Center of Fort Pierce, said Maj. David Thompson of the St. Lucie County Sheriff’s Office.

A July post placed on Facebook by Schreiber, who is Jewish, stated that, “IF AMERICA  truly wants peace and safety and pursuit of happiness they should consider all forms of ISLAM as radical. … ALL ISLAM IS RADICAL, and should be considered TERRORIST AND CRIMANALS (sic) and all hoo (sic) participate in such activity should be found guilty of WAR CRIM (sic)  until law and order is restored in this beautiful free country.”

Thompson told a news conference that Schreiber, who has a criminal record, was taken into custody on a street in Fort Pierce by authorities acting on tips from members of the community and aided by surveillance video taken from the mosque and elsewhere. He said the arson charge, coupled with a hate crime enhancement under Florida law, carries a sentence of up to 30 years in prison. Thompson said detectives were still questioning Schreiber on Wednesday evening, and he didn’t say if Schreiber had a lawyer.
