A man believed to be suffering from a mental health crisis barricaded himself inside an Uptown Minneapolis duplex for more than two hours before peacefully surrendering to police Monday.

Firefighters were called shortly after 1 p.m. to the duplex in the 2800 block of Garfield Avenue S. Initial Twitter reports from the fire department said the fire may have been started by an "emotionally disturbed" person on the first floor armed with an automatic weapon and a machete. Firefighters extinguished the small blaze and police blocked off the area.

Shortly before 4 p.m. the man, who was alone inside the duplex, was coaxed outside to a waiting ambulance.

Officer Corey Schmidt wouldn't confirm whether the man was armed, but said there will be no arrests, and damage to property was minimal. The streets have since been reopened.
