"We have handed over the body to the Japanese embassy officials," a police official said, adding that investigations into the case are still on.
Heroi Miata, who was living in Dhaka's Uttara area for 10 years, went missing in October last year after which her mother in Japan contacted the Japanese embassy in Dhaka.
Following a complaint by Japanese embassy officials in November last year, an investigation was launched and Bangladeshi police found that she was murdered on October 29 last year and was buried in a graveyard here as a Muslim under a false name.
It was found that she was abducted for ransom and later was killed as the culprits failed to realise the amount they demanded, a police officer had said.
Bangladesh last year witnessed the murders of another Japanese farmer and an Italian aid worker by suspected Islamists in separate incidents.
