I don't believe they actually did human sacrifice. They did, however, believe in telling the future (auguries) by watching the death throes of people dying in agony. To this end, they would take prisoners or slaves, hang them upright and burn them alive. The hanging skeleton often displayed during Halloween commemorates this pracitice (although most folks have no idea about the connection). I don't believe that technically qualifies as a sacrifice.

The Celtic druids did practice human sacrifice.
