Some Sneaky Sim

Some Sneaky Sim is the only burglar that robs Sims' houses in The Sims. He will only try to steal the expensive items that are in the household. A Sim can call the police once he arrives on a lot, though they will probably not arrive in time to arrest him. If he comes within range of a burglar alarm, it will automatically summon the police. Unlike burglars from The Sims 2 and The Sims 3, he will surrender and go peacefully when the police arrive.

Most of the times, the burglar will arrive late at night. But at some point, he may rob the Sims when they are still awake. At night, assuming your sims are asleep, time will automatically be set at the slowest speed, playing one of the two "danger themes." If one comes in the lot, Build and Buy mode are disabled until the burglar is finished stealing the Sims' stuff and a picture box may appear on the bottom-right of the screen, with text saying "Burglar!". If the family has a baby, there is a chance that he may take the baby with him. The burglar will spend his time stealing as many items as he can and escape before the cops arrive. If the police come after the burglar had robbed the Sims, they can't reimburse the loss. If they do, however, catch the burglar, they will receive §1,000 plus the current value of whatever was stolen. However. the police do not return the stolen items; they are taken away as evidence. At times, a family will be reimbursed for an item that the burglar did not manage to steal.

Burglars are attracted to families that do not have dirty houses, and have expensive items, such as a computer, or a television, but players can't actually predict when the burglar will come, nonetheless.

If a burglar steals an item, an automatic picture will be taken and sent to your family's photo library, along with a picture of him being apprehended if the police come. Once a burglar has stolen enough items to make him content, or when he gets spotted, he will try to escape. In doing so, Build and Buy Mode are once again, enabled. However, attempts to trap the burglar will be for naught, as he will disappear after time passes.
