Local Afghan community representatives have identified the suspect as an Afghan refugee who was known to have psychological problems after his wife died at a refugee camp in Greece.

The man had integrated into Western life and exhibited no radical behaviour in his habits, friendships or social media communications, according to Neves.

Authorities said the suspect remained in police custody at a Lisbon hospital and was not expected to appear in court for a week or more.

Police reported on Wednesday that he was shot when ignored an order to surrender and advanced toward the officers who responded to the Muslim centre.

Portuguese Interior Minister José Luis Carneiro said Tuesday the man arrived in Portugal through a European Union program that transfers asylum-seekers to member countries to help relieve pressure on Mediterranean nations such as Greece and Italy.

He said the man's wife died in a refugee camp in Greece, leaving him to care alone for three children, ages 9, 7 and 4.
