LONG LAKE — Authorities were searching the Lake Minnetonka area Sunday for three men who allegedly forced their way into a Long Lake home, tied up and beat the married couple who lives there and made off with their car.

The couple appeared to have been targeted, and investigators don’t believe Saturday afternoon’s attack was “a random act,” Wayzata police Lt. Mike Murphy said. He said there was no reason to think there was a general threat to the public, but that the suspects could be armed.

The suspects knocked on the couple’s door, entered and forced the couple into the basement, where they bound them in duct tape, authorities said. The woman freed herself after about 90 minutes and called police.

Investigators believe the men were in the home for most of those 90 minutes, during which time a gun went off and one of the suspects may have been struck by a bullet fired by his accomplice.

Police are looking for a red 2014 Kia Sorento with Minnesota license plate 723-KVL. The vehicle is the couple’s.

The husband was treated for back and neck wounds at a hospital, police said.
