A male driver has been given a formal warning after being found to be in possession.
At around 8.40pm on Tuesday 30 April four male youths were seen by police, in a parked car on Lowthorpe Lane, Nafferton.
On approaching the car officers noticed strong smelling smoke coming from the vehicle which they suspected was drugs-related.
A police spokeswoman said: “The officers searched the vehicle and found a small amount of herbal substance in a blue plastic bag in the driver’s trouser pocket, this was later identified as cannabis.
“The male admitted the drugs were his, he was made aware he would be recorded as responsible for committing that crime and was issued with a formal warning for the Possession Of Controlled Drugs (Cannabis).”
