Police in Japan are trying to track down two people they believe to have purchased cyanide capsules from an Internet website operating a suicide service.

The police said the website came to light when a woman customer died in hospital of cyanide poisoning.

They said the man who ran the service, a licensed pharmacist, also committed suicide after the police contacted him.

He had been charging about three-hundred-and-fifty dollars to have the capsules delivered by post.
