Canadian authorities have detained two people in connection to the Sunday Quebec City mosque attack. One man, identified by Canadian media as Alexandre Bissonnette, is believed to be the shooter.

Police detained one of the men at the scene of the shooting. Per local media reports, the second was apprehended shortly afterwards when he called the authorities distraught. It’s not entirely clear which one is Bissonnette. Contrary to initial reports that perhaps three shooters were involved, police say all suspects are in custody.

Details about the shooter’s motive are still sparse, but authorities believe it was an act of terror. One witness to the massacre described the shooter as having a Quebecois accent and shouting “Allahu Ackbar”– Arabic for “God is great”– but may have confused the shooter with another witness.

UPDATE – 12:24 p.m. EST: The Canadian police states that they only consider one of the detained men as a suspect, while the other is considered a witness:
