Barclays may have lost $220 mln in K1 fund -warrant

FRANKFURT Oct 29 (Reuters) - British bank Barclays (BARC.L) may have lost most of the nearly $220 million it invested with the K1 Global Sub Trust hedge fund run by German Helmut Kiener, who was arrested on Thursday, German authorities said.

"If Barclays had known of the suspect's plans, it would not have provided the K1 Global Sub Trust any funds for investment between 2006 and 2009," the warrant seen by Reuters says, adding the funds "are mostly lost as far as we now know".

The arrest warrant for Kiener outlining suspicions of fraud and breach of trust, dated Oct. 20, also said France's BNP Paribas (BNPP.PA) invested $60 million with K1 between 2007 and 2008. (Reporting by Patricia Uhlig, Writing by Michael Shields)
