An intruder wielding a knife attacked staff at the Animal Humane Society shelter in Golden Valley on Monday, after trying to remove a dog being held there.
The AHS confirmed to Bring Me The News that staff encountered the man just after 3 p.m., when he was trying to "forcibly remove a dog" that was being held on a bite quarantine in a non-public area of the shelter.
"During this incident he engaged physically with several staff members, threatening them and several others with a knife," the AHS said.
Golden Valley police say the 39-year-old man from Minneapolis was the owner of the dog, which had been impounded after the man was involved in a separate incident in Robbinsdale.
He had disguised himself as a volunteer to gain entry to the non-public areas of the shelter, but was subdued by staff and arrested by arriving police officers.
According to an arrest report, the weapon he wielded was a "double-bladed combat knife."
One male staff member at the AHS suffered torn ligaments in their hand as a result of the altercation, though nobody was injured by the knife.
The dog was recovered safely and returned to the care of the AHS.
In an email to volunteers seen by BMTN, the AHS said it would be reviewing its emergency plans and procedures in light of the incident.
The suspect is in custody awaiting charges.
