I agree with Raghavan Sir.
A landlord usually has a duty to protect the neighborhood of the rental property from the criminal acts of his/her tenants.
Since in this case the landlord has signed an agreement with the Tenant and in the agreement it is clearly stipulated that it will be tenants responsibility to ensure compliance and follow all rules related to his profession.
So, here the landlord normally is not liable for the actions of his tenants , unless he directs them to do something that results in liability, if he allows the tenants to create a nuisance on the property, he may be liable along with the tenants.
If neighbors named the owner of the property under the theory that a destructive nuisance on the adjoining property was causing harm to the locality and therefore the property owner, who allowed the nuisance to occur, shares legal liability for the damages.
In this case, the Landlord proactively has asked the Police to conduct a verification check on the tenant, then, i don't think any negligency had occured in landlord's part.
I will go with the suggestion provided by Raghavan Sir i.e "contest the same rather charges of the police".
Police do such steps only to earn some extra money. :)
