At least one person has been killed and five others wounded after multiple shots were fired at a church in southern California, authorities said, just a day after a white gunman killed 10 people at a grocery store in New York state’s Buffalo city.

The shooting was reported shortly before 1:30pm on Sunday at the Geneva Presbyterian Church located in the town of Laguna Woods, about 80 kilometers (50 miles) southeast of Los Angeles, the Orange County Sheriff’s Department said on Twitter.

A man died at the scene and four others were critically wounded, while a fifth injured person suffered minor injuries, officials said. All the victims were adults.

Deputies detained a suspect, an adult male, and recovered a weapon at the scene, officials said. It was not immediately clear where inside the church the shooting had happened.

About 30 people witnessed the violence, said Carrie Braun, a sheriff’s spokesperson. The majority of those inside the church are believed to be of Taiwanese descent, she said.

Investigators were looking at many factors, including whether the bloodshed could be a hate crime and whether the gunman was known to the church community, she said.
