Aug 7 (Reuters) - A Moscow court on Monday sequestered Goldman Sachs assets in Russia including its 5% stake in Russia's largest toy retailer, Detsky Mir, at the request of the Otkrytie bank, which says Goldman Sachs owes it 615 million roubles ($6.45 million), court documents showed.

Otkrytie has said Goldman Sachs cited sanctions introduced by the United States and Britain over Moscow's war in Ukraine in failing to settle the debt.

A hearing in that case is scheduled for Sept. 7.

In addition to the Detsky Mir stake, the court's injunction provided for the seizure of all Russian stocks owned by the Goldman Sachs III SICAV fund, as well as the bank's ownership rights to several trademarks, pending resolution of the debt case.

Goldman Sachs did not immediately reply to a request for comment. (Reporting by Reuters; Editing by Kevin Liffey)
