Officers have swooped on nine houses in Ovenden, Halifax, to tackle drug dealing.
The week-long operation saw Halifax North and East neighbourhood policing team acting on information received from the public.
Officers seized around 500g of what is believed to be amphetamine as well as drug dealing paraphernalia.
Four mountain bikes believed to have been stolen were also seized.
Chief Inspector Kate Jowett of Calderdale Police, said: “This operation was launched after members of the public passed on specific information about suspected criminal activity in their community.
“If people tell us what is happening in their area then we will take action. This operation was a big success - not only did we seize suspected drugs but we also significantly disrupted criminal activity in the area.”
