Police in Wisconsin have been searching for days for a highly agitated man they say stole a cache of firearms from a gun shop and threatened public officials, including President Donald Trump.

Joseph Jakubowski, 32, sent a menacing, anti-government and anti-religion manifesto to Trump on April 4, the same day he stole a large quantity of high-end handguns and rifles from a gun shop in Janesville, according to the Rock County Sheriffs Office.

Jakubowski has been highly agitated recently regarding a variety of political issues, the sheriffs office said.

About 30 minutes after the break-in at the Armageddon Gun Shop last week, Jakubowskis station wagon was found on fire, the result of arson, the sheriffs department said in a statement.

Its unclear if Jakubowski is hiding in the southern part of the state or has fled the area, authorities said. Federal, state and local departments have supplied officers to help with the manhunt.

He also made threats against schools, but didnt mention a specific location, according to the sheriffs office. Janesville School District canceled classes on Friday as a precaution. More officers have been patrolling near churches, because of the unspecified anti-religious remarks in the suspects manifesto, the sheriffs office said over the weekend.

Authorities on Friday released video appearing to show Jakubowski addressing en envelope to Trump and buying postage to send his 161-page manifesto to the White House.

To anybody that got this letter, you might want to read it, the man police identified as Jakubowski says as he walks through a parking lot after visiting the post office. Revolution. Its time for change.

The sheriffs office said the manifestoincludes grievances against government and personal angst toward anyone or anything other than natural law or rule, according to CNN.

A second man also is heard on the video.

D-day. Today is the day, says the second man off camera as the video follows Jabukowski. So remember this face.

Jakubowski was imprisoned in 2009 for trying to seize a cops gun, The New York Times reported. He has long harbored anti-police attitudes, his stepfather said, and may be trying to provoke an officer into killing him, according to NBC News.

Jakubowski is white with brown hair and green eyes. He stands 5-feet-10 and weighs 200 pounds, according to the sheriffs office. Hes described as armed and dangerous.

The FBI is offering up to $10,000 for information that leads to his capture. Tipsters can call the bureau at 800-225-5324.
