A CANNABIS factory has been discovered in a Grantham house - but the culprits are nowhere to be found.
The cultivation operation was set up in a rented house in Victoria Street, and later abandoned.
Although much of the grow had already been cropped by the time police executed a search of the property on Friday, around 400 plants were recovered.
Police have issued a stark warning to landlords to be wary of potential tenants offering cash up front.
Lincolnshire Police spokesman James Newall said: “Landlords and lettings agencies must be careful about who they let their properties to, and they should make sure all the proper checks are done and references gathered, and to physically check properties on a regular basis.
“Anyone who wants a cash in hand arrangement is someone to be suspicious of.”
Rooms in the rented terraced house were converted into growing facilities with hydroponics lighting, and the electricity mains supply bypassed to run the lighting and extraction systems.
Such alterations are costly for landlords to put right.
Mr Newall said: “The electricity has been bypassed and a ventilation system has been rigged up, causing significant damage to the property which potentially could cost thousands of pounds to repair.”
Neighbours have told police the tenant of the house has not been seen for some time, prompting detectives to issue an appeal for information as to his whereabouts.
Anyone with information is asked to call Grantham Police Station on 0300 111 0300 as soon as possible.
