Four people have been arrested for suspected drugs offences in Devon.
Three women and a man were arrested in the Totnes area when warrants were served on Wednesday.
During searches, more than 50 litres of a suspicious substance, believed to be a hallucinogenic Class A drug, was found, police said.
The substance was being forensically examined. Two women were released on bail. The man and the third woman remained in custody, police said.
The women, aged 31, 33 and 37, and the 48-year-old man were arrested on suspicion of conspiracy to supply drugs.
Devon and Cornwall Police said the substance found was believed to be Dimethyltryptamine (DMT), a hallucinogenic drug sourced from Amazonian plants and usually taken in a liquid form.
The substance had been imported from Brazil, police said.
