We went to this property once in august and another time in september last year, the building was completely empty. we went last night and there were lights switched on up on the top floor, we got closer and could hear voices in the building upstairs. suddenly a car came out of no where with no lights on and told us 'not to go in, someone has been living in there for over a year and some new tenants are in, as soon as you hit the steps thats it, he said theres cameras up and we look like nice people' so we continued round a different building until he had gone. we went back to our cars, we decided to go back and have a look. we had a nosey round and it was dead silent, thought we saw a shadow outside. on our way back to the cars the other vehicle came shooting down the road and looked at the entrance with a torch and continued to drive around the building with no lights on really slow to see if im guessing if he could see us. felt very weird and strange. he lied about how long they had lived there.
