A man visiting a Catholic church in Albuquerque, New Mexico, stabbed four choir members as they were singing the closing hymns of a Mass on Sunday, police said.
Parishioners at St. Jude Thaddeus Catholic Church jumped on the unidentified man after the attack and were restraining him when police officers arrived just before noon local time (1800 GMT), Albuquerque Police spokeswoman Tasia Martinez said.
The four injured choir members were taken to local hospitals with non-life-threatening injuries, police said.
Martinez said the man arrested for the attack was not a member of the church and the reason for the stabbings was not known.
