A 16-year-old boy has been arrested for allegedly stabbing two men, one of them fatally, outside the Church of Scientology's headquarters in Sydney, Australia, police said.

The teenager, whose name has not been released, was being escorted from the church in Chatswood on Thursday afternoon when he pulled out a "very sharp kitchen knife" in the driveway, an officer said during a press conference outside the religious center.

"This very unfortunate matter is in the hands of the police. We cannot make any further comment beyond the fact that the victim was a beloved member of our Church," a statement from the church read, adding they are "providing the police with any assistance needed in their investigation."

Australian police said they believe the suspect has a family member who attends the church. The teenager was asked to leave the center because of a "domestic incident" that occurred on Wednesday, according to officials.

“It does not, as far I know, relate to the Scientology premises here,” police said about Wednesday's incident. “However, resulting from that incident, staff made the decision that he should leave the premises.”

His relative was at the church during the incident, but police are not sure if the teenager was able to make contact with that person.

The suspect was arrested outside the church and is being held at the Chatswood Police Station.
