FOND DU LAC, Wis. (From news reports) - A 34-year-old Fond du Lac man was taken into custody by SWAT on the roof of International Paper.

According to police, officers first responded Tuesday morning, May 14, around 10:12 a.m. to a Fleet Farm on 800 S. Military Road for reports of a person wearing camouflage clothing flashing what appeared to be a law enforcement badge while walking around the store.

The person ran off eastbound from the store and eventually made it to the railroad tracks where he ran southbound. As Fond du Lac Police officers and Fond du Lac County Sheriff's Office deputies got into the area they saw the man climb up an exterior ladder on the side of the International Paper building to the rooftop.

Initially, police said the man stood at the edge of the roof and yelled back at law enforcement while they attempted to talk with him and build a rapport.

FDLPD Officers were able to identify the individual as a 34-year-old Fond du Lac resident known to FDLPD from prior contacts. The man was exhibiting bizarre and erratic behaviors, severe agitation, and threatened violence toward law enforcement. Police said the man also has been recently exhibiting escalating behaviors around the City and the FDLPD was looking to take him into custody for felony retail theft, criminal trespass to a dwelling, criminal damage to property, and a probation/parole warrant.

During initial negotiations, FDLPD worked with staff from International Paper and requested that all employees shelter in place. As more law enforcement resources arrived, Officers and Deputies were able to assist with the evacuation of employees from the business.

FDLPD deployed the Technology Response Group (Drone/Robot Unit), Bear Cat (armored rescue vehicle), a FDLPD K9 unit, assembled a combined team of FDLPD and FDSO Crisis Negotiations members, and the FDLPD Co-Response Mental Health Unit consisting of a Social Worker and Mental Health & Wellness Police Specialist.

After over six hours of negotiations and exhausting all options, the FDLPD SWAT team was activated along with a FDSO K9 Unit and one additional FDSO SWAT member. During the standoff, the man armed himself several times with improvised weapons (i.e. rocks, metal rebar stakes, etc.).

FDLPD SWAT accessed the roof and deployed a less-than-lethal impact munition, a 40mm sponge round, and chemical munitions before taking him into custody.

"The goal in any situation is to de-escalate and bring a peaceful resolution so that everyone is safe. Even when Officers attempt to de-escalate a situation, sometimes factors beyond the control of an Officer can result in force becoming necessary. The use of a less-than-lethal impact munition and OC chemical munitions helped resolve this high-stress encounter while reducing the risk of injury to the individual and Officers," police said in a statement.

The 34-year-old man was transported by the City of Fond du Lac Fire/Rescue to the hospital for further medical evaluation.

No further details or information are being released at this time.
