Police Line

So today after my morning class finished, i wanted to go to OCBC to take money in fortune center. But when i cross the street from Sunshine Plaza to Big Hotel, there are many police around and the police's car is beside the fortune center. Then when i'm at the atm center, i saw from far the police set a police line on both traffic light in front of Big Hotel. When i get back, i saw from nearby the police was taking apart the big black bag. I think there's a bomb inside the bag but then there was nothing in it. So after that the police take off the police line and i go back to the school.
