Almost 50 arrested at Vic music festival

Police have arrested 48 people and seized drugs at Melbourne's Future Music festival.

Police used sniffer dogs in the operation that seized drugs including ecstasy, cannabis and amphetamines on Sunday.

Police said 45 people received drug diversions and three people were given cannabis cautions.

Senior Sergeant Mark Pilkington said the passive alert detection (PAD) dog operation detected 44 of the 48 arrests and enabled police to seize drugs before they made it into the event.

"These drugs are manufactured by criminals and people have no idea what they are taking or the real risks involved," he said.
