The father would be asked about and determined; mostly there will be no police involvement especially in cases of statutory rape where the father is of the same age as the pregnant teenager. Any child who becomes pregnant should automatically be referred to social services because she herself becomes a 'child in need' by the very fact she is a mother under 16. We automatically refer to social services for all under 16 pregnancies and sometimes for 16-18 year olds dependent on circumstances (big difference between mature, well supported/married 18 year old and someone who was 16 last week and to all intents and purposes still 15 but for a few days). I would have serious questions about the safety and wellbeing of this 15 year old if she was on my caseload. It's not just about 'wanting to be a housewife'. Legally at 15 you are a child.
