Yes it is. Housebreaking is an aggravation of theft where a person enters a building or part of a building without permission and proceeds to steal property from within. For many people this means that someone has entered your house without permission and stolen property from inside your house.
The whole body does not have to enter the house, so if someone puts their arm through the letterbox and steal keys for example, this is a classed as a Housebreaking
Examples of housebreaking:
B smashes a patio door and opens it and goes into living room and steals a TV and DVD player and leaves the house.
B puts his hand through an open window and steals a purse that has been left on the kitchen unit.
If you have suffered from a housebreaking, please contact the police straight away and try not to touch anything that you think the offender may have touched.
