The Singapore home ministry said a man will be charged tomorrow with voluntarily causing grievous hurt with a dangerous weapon. The police will seek a court order for him to be remanded for psychiatric evaluation.

The ministry said the man is believed to have acted alone, and there is currently no evidence to suggest that the incident was a religiously motivated attack or linked to terrorism.

“Nonetheless, the police have stepped up patrols at places of worship to provide assurance to the public,” it said.

On Saturday, parish priest Christopher Lee, 57, was stabbed near the mouth by a knife-wielding man while celebrating the 5.30pm mass. He is reportedly in stable condition.

The suspect was disarmed by two members of the congregation and later arrested by police officers.

Local media identified him as Basnayake Keith Spencer, a 37-year-old Singaporean with a history of assault and drug-related offences.

The Archbishop of Singapore, Cardinal William Goh, said the church will revisit the security protocols already in place in its parishes.

“However, we must also recognise that our churches are public spaces,” he said, Bernama reported.

“Going overboard with security measures may discourage the faithful from coming to worship due to the inconvenience they would have to endure.”
