The bomb detonated Saturday night at 8:10 pm local time (9:10 pm CET) on downtown Bishop Street. Nobody got hurt. A warning had been given 15 minutes before the explosion, when police began clearing surrounding buildings.

Hamilton reported that, among other things, hundreds of hotel guests and many children of a youth club had to be brought to safety. The car in which the bomb had been placed had therefore probably been stolen nearby shortly before.
