LONDON, Sept 3 (Reuters) - A private equity fund run by Goldman Sachs Asset Management (GSAM) has bought a minority stake in multi-strategy hedge fund firm LMR Partners, one source familiar with the matter said on Monday.

A spokesman for LMR Partners, which has offices in London, Hong Kong and New York, declined to comment. A spokesman for Goldman Sachs also declined to comment.
