"There was an incident yesterday where a stranger was buzzed into the building and was going door to door trying to get in people's units. Luckily one of the residents saw what was going on and started questioning him, which eventually scared him out of the building.
This gentleman asked our resident if he could get into the unit because he was there to do some electrical work, which was clearly not true. A few minutes later the resident noticed him trying to open other people's doors. He was not from ComEd and was not authorized to be in the building. He ended up leaving and walking outside to two friends that were waiting for him.
I can't stress enough how important it is NOT to buzz anyone in that you aren't expecting or that you don't know. Sometimes FedEx and UPS will try and buzz every unit just to get into the building so they can leave a package. If you are not expecting a delivery, DO NOT buzz them in. The person expecting the package will have to make arrangements to receive it.
Spread the word to your neighbors if you see them."
If anyone ever notices any suspicious activity, I would suggest calling the police and then notifying management. Thank you in advance for your cooperation."
