Sorry if it is old news.
7D Tanglin Hill or OBH has gone the way of CGH and is now officially an "arrest if trespass" zone. Please spread it around in case anyone is planning photoshoots there. Guess this is what happens when such places become very public knowledge and people go there without being responsible like taking out the trash they bring in or moving objects here and there for "composition". Its also been flooded with photographers in recent time who use it for their abandoned building shoot and most of them might be inexperienced with the danger of doing photoshoot in abandoned locations. Thankfully have a few more places that are similar but still very low key.
