When I got back to Antonine Heights last night around 1830, I saw about 12 teenagers coming out of the building. It seems that they have congregating in the stairwell at the top of the building and smoking. I checked the security doors in the basement and they are working so they must have come in throught the main entrance. If you are a resident in the block, please don't let anyone in you don't know, otherwise the block will become a hangout for all the local youths. Thank you!
