LONDON (Reuters) -The hedge fund short selling partnership of Gotham City Research and General Industrial Partners (GIP) said on Wednesday it has taken a short position in the real estate investment trust, Iron Mountain <IRM.N>.

The company did not immediately respond for a request for comment.

Daniel Yu and Cyrus de Weck said Iron Mountain's leveraged investments into data centers do not match what the firm has available long-term to spend.

As of 15:55 GMT the Reit shareprice was down 5%.

The team is known for their research on SES Imagotag, now Vusion Group and Spanish medical company, Grifols.
