Lincolnshire Police have responded to concerns over the supply of controlled drugs in premises in Lincoln.
Police used search warrants in two licensed premises believed to be supplying drugs overnight between December 21 and 22.
A staff member at one of the premises was arrested on suspicion of possession of controlled drugs with intent to supply. He has been interviewed at Lincoln Police Station and released on police bail pending further enquiries.
Two other staff members have since been arrested for further possession of controlled drugs offences. They too have been interviewed.
A quantity of what is currently believed to be cocaine was recovered from both of the units.
Insp Mark Garthwaite said: “This action was taken in response to community concerns and we hope it sends out a clear message to those enjoying themselves in Lincoln over the festive period.
“We are also grateful for those people who share our concerns and provided us with the information on which we were able to act last night.
“The distribution and consumption of controlled drugs will not be tolerated and we will take tough action.”
