The document listed Arthur's blood status, the status of his family, and his security status within the Ministry. Because he was a known member of the Order of the Phoenix, Arthur was under constant surveillance. The Ministry also believed that there was a strong likelihood Harry Potter would try and contact him.
BLOOD STATUS: Pure-blood, but with unacceptable pro-Muggle leanings. Known member of the Order of the Phoenix.
FAMILY: Wife (pure-blood), seven children, two youngest at Hogwarts. NB: Youngest son currently at home, seriously ill, Ministry inspectors have confirmed.
SECURITY STATUS: TRACKED. All movements are being monitored. Strong likelihood Undesirable No. 1 will contact (has stayed with Weasley family previously).
