Salt Lake City police were in a three-hour standoff outside a shed behind a Salt Lake City home before finding out there was nobody inside.

The standoff started Thursday after police got a report from a woman living inside the house that she thought she saw her roommate's estranged boyfriend enter the shed with a gun.

Officers secured the area, but after clearing the house and sending K-9 dogs to the shed, they found it was locked and there was no one there.

Some neighbors had been evacuated and police shut down a portion of a city street near the house.
