A British grandad jailed for smuggling drugs into Japan has died in prison aged 67.

Frank Rodway was jailed for nine years in 2019 after £1million of amphetamines was found in his bag when he landed in Tokyo.

The grandfather, from Salford, said he fell for an inheritance scam and was unaware of the bag's contents.

Frank was reportedly persuaded to fly to Mali to sign 'important documents' - and was then put on a plane to Japan where he was arrested.

Daughter Laura, who has spoke to  The Sun, claims drugs were hidden in his luggage without his knowledge and that he has "never been further than Scarborough before".

She has now slammed the UK Foreign Office, accusing them of leaving him "to rot" in the Japanese jail.

Laura said: "They left him to rot there — it’s disgusting."

She has also reportedly been told she will need to pay £17,000 to bring his body home.

Before his death, Laura told the Sun she did not even know the retired plasterer had left the country until he sent her a text while on his way to Japan.

Shortly after she got a phone call from the Foreign Office saying he had been arrested.

It was when Laura checked her dad's emails she found the communications from the West-African based gang.

Frank was reportedly persuaded by the crooks the to fly to Mali from Manchester, via Morocco and paid for his flight.

The final email sent just before his arrest said: “By now you must have connected to Japan to complete your dealings and release your inheritance fund valued at US$10.5million.”

Japan has some of the strictest drugs laws in the world and Frank's haul would have a value of about £1m on the street.

The Foreign Office has been approached for a comment by the Mirror Online.
