South Korean prosecutors are making a fresh effort at arresting Daniel Shin, a financial technology entrepreneur who helped to set up the Terraform Labs crypto project that suffered a $60 billion wipeout last year.

The prosecutors’ office in Seoul on Monday confirmed the renewed push to detain Shin but didn’t provide further details. The development follows the arrest of Terraform Labs’ other founder Do Kwon in Montenegro last week..

Shin’s lawyers previously said that he split from Terraform Labs in 2020 and hasn’t been involved in its operations since. A South Korean court in December rejected an earlier effort by prosecutors to obtain an arrest warrant for him, saying it was difficult to believe he poses a flight risk or would destroy evidence.

Prosecutors in Seoul indicated last year that Shin faced charges including fraud, breach of duty, violation of capital-markets law and illegal fund-raising.
