A mother who dumped four of her babies in buckets filled with concrete that she then kept in her apartment for two decades was arrested in Japan on Tuesday.
Mayumi Saito, 53, told investigators she had given birth to the infants between 1992 and 1997, a police spokesman told AFP.
Saito handed herself in at an Osaka police station on Monday and confessed, saying she did not think her desperate financial predicament made it possible for her to look after the children, local media reported.
