Recent events involving illegal activities taking place within the premises have come to my attention, as reported and documented by local law enforcement. This correspondence serves as an official warning and a reminder of the obligations outlined in your lease agreement. As you are aware, engaging in any form of illegal activity within the rental property is strictly prohibited under the terms of your lease agreement. It is crucial to emphasize that such activities not only jeopardize the safety and well-being of fellow tenants but also violate local laws and regulations that all residents must abide by.

I understand that people can make poor choices or be driven down the wrong path at times, and I urge you to consider the consequences of your actions. Your engagement in any illegal activities goes against not only the terms of your lease but also the community's standards and expectations we strive to maintain. Based on the severity of the situation, I want to make it clear that, should any further evidence of your involvement in illegal activities within the premises come to light, your lease agreement will be terminated effective immediately. This would result in the revocation of your tenancy rights, and you would be required to vacate the property within [specific time period]. Furthermore, it is vital that you understand the potential legal ramifications of your actions.
