CANNABIS plants and resin were seized during two early morning raids in Oxford.
Police found 60 plants at a house in Alice Smith Square, Littlemore, and a “large” amount of cannabis in George Moore Close, off Iffley Road.
A 25-year-old woman and two men, aged 31 and 32, were arrested shortly after the simultaneous linked raids at 7am.
All three were held on suspicion of cultivation of cannabis, possession of class B and C drugs and abstracting electricity.
Pc Ashley Gardner said: “It was a significant amount of cannabis overall.
“A hydroponic set-up was discovered at the address in Alice Smith Square and a large quantity of cannabis was discovered at the address in George Moore Close.”
Police are appealing for witnesses and last night said they did not know the value of the drugs seized.
