Simondet was found by the state patrol at an Oakdale Denny's after reports were given of a man yelling and attempting to stop traffic, according to KARE 11.
A sheriff's deputy tased Simondet when he resisted being taken into custody, the station reported. He was taken to Region's Hospital.
His brother Matt said that the Simondet family was not upset about the tasing.
"We understand it takes extreme measures to deal with these situations at times." Matt Simondet told KARE 11. Christopher "is very strong and would not have gone easily.""We want to thank everyone for their efforts with this!" Nikki Schug, a friend of the family, wrote. "We could not have done it without you."
Simondet left his bulldog, Diesel, at the Bloomington Animal Shelter on Wednesday.
Original post, 3:30 p.m., Oct. 17: Family and friends of St. Louis Park resident Chris Simondet say he's been missing since Sunday afternoon and are looking for help in locating him. He's believed to be accompanied by his 90-pound Renaissance bulldog, Diesel.
The city of St. Louis Park issued a "missing person alert" to the public on Facebook.
"Chris is bipolar, without medication and probably disoriented," family friend wrote in a message shared by the city. "If you see them, please call 911."
Simondet, 30, went on a walk Sunday afternoon near Minnetonka Boulevard and Highway 7. The two have since been spotted in St. Louis Park and Hopkins.
Simondet is 6-foot-1, about 185 pounds, with brown curly hair. He was last seen carrying a backpack and blanket and wearing a hoodie, a two-layered jacket—camo or black in color—and light blue tennis shoes.
Minneapolis police are asking anyone with information about Simondet to call 911, according to Fox 9.
