A woman has been arrested for destroying her former partner's violin collection and 70 bows, together worth 105.9m yen ($950,700, £770,000).
The 34-year-old suspect broke into his apartment in Nagoya and wrecked the instruments, police said.
The incident took place in 2014 in the midst of their breakup but the woman has only just been arrested.
Her 62-year-old former husband is said to have been both a maker and collector of violins.
The most valuable instrument among the 54 casualties was an Italian-made violin worth 50m yen, the Kyodo news agency said.
