Newly released video shows the man suspected of stealing firearms from a southern Wisconsin gun store mailing an anti-government manifesto to President Donald Trump.

More than 150 law enforcement officers are searching for 32-year-old Joseph A. Jakubowski of Janesville, Wisconsin.

Investigators believe Jakubowski stole 'a large quantity of high-end handguns and rifles' from a Janesville gun shop Tuesday night, said Rock County Sheriff Robert Spoden in a statement.

Public schools and local colleges were closed because of the 'non-specific threats.'

A 15-minute-long social media video released Friday shows the footage of Jakubowski mailing a letter to the president.

He poses with the envelope addressed to the president and mails what appears to be the anti-government manifesto.

It was filmed by a friend who eerily says: 'Y'all have no idea what's about to happen,' as they wait for stamps at the post office.

As Jakubowski stamps the envelope his friend says: 'You'll never forget this face, ever.'

As they walk out of the post office, Jakubowski tells the camera: 'Anyone who got this letter, you might want to read it. There you see it's good s***. Revolutionary. It's time for change.'

His friend says: 'It's D-day. Remember this face,' to which Jakubowski responds: 'F*** the system,' before smiling at the camera.

Jakubowski marks the time he mailed the letter as April 4, 2017 at 5.43pm, hours before he is accused of robbing the gun store.

Authorities said he also has acquired a bulletproof vest and helmet.

Jakubowski became the prime suspect in the burglary of Armageddon Gun Shop after a car registered to his name was found burning on a rural road about three miles from the store within a half hour of the break-in.

Newly released photos show Jakubowski at a Mobil gas station at 1pm on Tuesday and his torched car.

Spoden said an associate of Jakubowski told authorities he had been 'agitated' by national politics and 'recently verbalized a plan to steal guns and use them in an unspecified attack.'

The associate also said Jakubowski had made non-specific threats toward schools and public officials, according to the sheriff.

Public schools in Janesville and nearby Milton canceled classes Friday as officers combed the surrounding county.

The University of Wisconsin-Rock County and Blackhawk Technical College were also closed.

Spoden said Jakubowski recently sent a 161-page anti-government manifesto to the White House and gave a copy to one his associates, who turned it over to police.

'When you look at the document that he wrote, it's really a long laundry list of injustices he believes that the government and society and the upper class have put forth onto the rest of the citizens,' Spoden said, declining to offer details.

Jakubowski has had several run-ins with law enforcement over the years.

Most were for traffic violations, though he has previously resisted arrest and once tried to disarm an officer, said Janesville Police Chief David Moore.

A $10,000 reward has been offered for information leading to Jakubowski's arrest.

Jakubowski is believed to be armed and dangerous. Anyone with information about his whereabouts is urged to call 1-800-CALL-FBI (225-5324).
