Dan Adamescu, one of Romania's richest and controversial businessmen serving a prison sentence for bribery, has died. He was 68.

Daughter-in-law Adriana Constantinescu told Romania TV that Adamescu died Tuesday in a private hospital where he had been transferred from prison for treatment for an infection.

In May, Adamescu was sentenced to four years and four months in prison for instructing his lawyer to pay bribes of 20,000 euros ($20,150) to judges in December 2013.

The bribes were related to insolvency cases involving his companies. A judge got more than 12 years imprisonment.

Adamescu's lawyer reportedly threw himself in front of a subway train after the judge's 2014 arrest.

Adamescu was reportedly worth 850 million lei ($20.3 million) in 2015. He owns the Romania Libera newspaper and an insurance company.
