A midtown neighborhood was in lock-down for eight hours Monday when police thought a violent man had barricaded himself in a home.

The house turned out to be empty and the man likely left before police arrived.

The incident started just before 2 p.m. when officers responded to a 911 call from home in the 1200 block of North Tucson Boulevard, north of Speedway.

A woman was waiting for officers outside the home and told them she and two men had fought, said Sgt. Chris Widmer, a spokesman for the Tucson Police Department. The men, she said, were still in the house and they had access to several weapons.

The woman was taken to the hospital with minor injuries and one of the men came out of the house and was detained by officers, Widmer said.

Believing one man remained in the house, officers closed off Tucson Boulevard between Speedway and Drachman Street and Helen Street between Forgeus and Norton avenues.

It was 10 p.m. before TPD determined the house was empty and residents were allowed to return home.

“Given the information we had at the time, for the citizens in the area and the officers we had there, we had to treat it with due caution,” Widmer said of keeping streets blocked.
