Two men have been arrested on suspicion of drugs offences after they were found reportedly moving cannabis farming equipment into a property in North Ormesby.
Officers on patrol spotted the pair moving items from a van into an address on Beaumont Road on Monday evening.
It is believed the property was being prepared for a future cannabis farm.
The men, aged 28 and 30, are being questioned on suspicion of being concerned in the supply of cannabis and abstracting electricity.
Sgt John Sproson, from Cleveland Police, said: “Local residents in the North Ormesby area have told us that they are concerned about drugs activity and we are patrolling the area to tackle the issue.
"Yesterday, officers were in the right place at the right time."
