I have applied for a job with my local police force. As part of the process I am required to complete vetting forms. A question on the form is about brothers/sisters and their addresses. My half brother who I lived with up until the age of 20 with our mum has a criminal record for various offences ranging from theft, drug offences to possession of a firearm. He has never been to prison but as a youngster he did get into trouble a bit. He hasn't been arrested for well over 10 years. My question is will this affect my application?
