Prosecutors have released the father of Japanese television personality Rola due to a lack of evidence backing his arrest on suspicion of fraud.

"At the moment, there is no evidence that can lead to an indictment," the Tokyo District Public Prosecutor's Office said Friday in explaining why it is releasing the 54-year-old Bangladeshi national, who was identified by the police as Jurip Al-Asa.

The investigation will continue on a voluntary basis.

Jurip was suspected of swindling around ¥875,000 in benefits from Setagaya Ward.
