A 26-year-old man, indicted for allegedly beating his 25-year-old girlfriend to death, had been instructing her to go on dates with other men for money so that he could use the cash for his investments, investigative sources said Thursday.

Tokyo police have issued a fresh arrest warrant for Ryotaro Masuda, who describes himself as a personal investor, for earlier violence toward the woman resulting in injury.

Investigators suspect Masuda had been repeatedly beating her to force her to date other men for cash — called papakatsu, which loosely translates to dating older men for moneyso that he could use the money for his investments as well as for personal use.
