(St. Cloud, MN) -- St. Cloud police say a father tried to kidnap his own children Wednesday morning. The 28-year-old man was said to be armed when the four children, ages 18 months to 12 years, were taken from their mother. A female accomplice allegedly used a Taser on the mother. The children were found safe in Grand Rapids and the father and two others were arrested. A fourth suspect was caught later in Minneapolis. The children remain in protective custody.
