The video shared on the Sniff Off Facebook page appears to show police forcing a drug dog to sit and indicate a person for drugs.
The video was taken at Sydney Showground on Sunday evening during the Epik Music festival.
Founder of Sniff Off and Greens MP David Shoebridge said:
“Drug dogs get it wrong almost 70 percent of the time and this video shows you one of the reasons why.
“The NSW Police use their drug dog program as an excuse to submit people to the humiliating and traumatising strip searches at random.
“We are constantly hearing from young people that the drug dogs haven’t indicated they have drugs but they are still searched by police.
“Forcing a drug dog to sit as a way of trying to justify a search is so obviously wrong that maybe even the Police Commissioner will do something,” said Mr Shoebridge
