In 2007, Njogu wanted a review of the salaries of the members of parliament. Kenya is very poor, but the members of parliament received a lot of money. The police attacked Njogu and took her to jail. Njoogu and the others who were arrested filed a Constitutional reference. It was called "Ann Njogu and others versus the State." It said the police could not keep a Kenyan citizen in jail for more than 24 hours.
