Police have staged four drugs raids in York.
Officers targeted properties in the Fulford area on Saturday and seized drugs and made arrests.
The South and East York Neighbourhood Policing Team led the operation on Saturday.
They executed four Misuse of Drugs Act warrants with the support of police specialist operation teams “in response to a suspected drug supply network operating predominantly in the Fulford area of York”.
A North Yorkshire Police spokesperson said: “A substantial amount of Class A and B drugs and an offensive weapon were seized from the properties.
“At this time, three persons have now been arrested for various drug supply offences and have been released on bail whilst our enquiries continue.
“A fourth person remains outstanding for the same.
“Our team will continue to tackle and disrupt this type of criminal activity wherever possible.”
It comes after a week-long crackdown on county lines drug dealing earlier this month, which resulted in 26 arrests and the seizure of £70,000 in cash, suspected drugs, weapons and mobile phones.
