Robbery Case in Cypress

Just now in the evening my housemate came back from outside...
Suddenly he told me that there is a robbery case in Cypress second floor this morning...
He knew it because she saw the victim in the lift & told him everything...
He just briefly told me that the robber get into the house & the girl's hand is injured by the robber by using knife...
And the case is happened on 9 something in the morning...
Lately, Sg Long is having a lot of robbery cases...
This makes me feel scare about it...
Some more now is study week & there is not much people staying here...
Our house just having one lock & it is very very unsafe...
Now, when want to go out or come back home also must watch around first...
