Two American men still jailed in Japan in death of Irish exchange student Nicola Furlong

In 2012, Japan's capital was ranked the world's most expensive city for expatriates, bumping down last year's number one, Luanda, Angola. The ranking was part of a survey by global employment consultancy firm Mercer. As New York City is a huge economy and international hub, it was used as a base city for the survey, explains Miriam Siscovick of Mercer.

(CBS/AP) MEMPHIS, Tenn. - Two American men remain held in a Japanese prison in connection with the fatal strangulation last month of 21-year-old Irish exchange student Nicola Furlong, CBS affiliate WREG reports.

Japanese police took 19-year-old Memphis man Richard Hinds into custody along with 23-year-old dancer James Jamari Blackston, shortly after Furlong was found strangled on May 24 in a Tokyo hotel after a Nicki Minaj concert. 

By law, suspects in Japan can be held for a considerable period of time without a charge as investigators build a case.

Hinds and Blackston are not charged with Furlong's death but are detained under suspicion of giving alcoholic drinks to Furlong's friend and then sexually molesting her in a taxi to the hotel, WREG reports.

Police have not officially named Hinds as a suspect, since the 19-year-old is considered a minor under Japanese law.

Friends said the men were in Japan as part of the touring group of a Japanese pop star.
