Multiple people were shot, including one fatally and wounding at least four, at a church in Laguna Woods in Southern California, authorities said on Sunday, adding that a suspect was detained in connection with the shooting. A male suspect in his sixties was arrested.
Churchgoers at a luncheon banquet reportedly captured and tied up the shooter.
It was at least the second mass shooting of the weekend in the United States, which has been plagued with gun violence in recent years. In Buffalo, New York, on Saturday, a white 18-year-old man opened fire at a supermarket in a mostly Black neighborhood, killing 10 and wounding three in what authorities described as a purely racist attack.
"Dispatch received call of a shooting inside Geneva Presbyterian Church at 1:26pm. Four victims have been critically wounded, one with minor injuries," the office of the sheriff of Orange County, California, said on Twitter.
All of the victims were adults and were being taken to the hospital, the tweet added. One victim died at the scene.
Laguna Woods is a community in Southern California of about 16,000 people.
Authorities in California have not made any statement regarding a possible motive in the church shooting.
