Private US security firm Xe, formerly known as Blackwater International, has been bought by a group of investors.

New York-based USTC Holdings said in a statement it will acquire Xe and its core operating subsidiaries, but did not disclose the price or terms.

USTC Holdings is an investor consortium led by private equity firms Forte Capital Advisors and Manhattan Partners.

Xe’s current owner Eric Prince will sell his entire stake in the company and “will not be involved in the management or operation of the company,” USTC Holdings said.

“The company going forward will be managed by a board appointed by the equity owners which will include independent, unaffiliated directors.”

The New York Times reported the sale came after the State Department threatened to stop awarding contracts to the company as long as it was owned by Mr Prince, a former Navy Seal.

The company, once the best-known security contractors in Iraq and Afghanistan, has come under pressure since Blackwater guards were accused of killing 17 civilians in Baghdad in 2007.

Mr Prince put the company up for sale in June and moved his family to Abu Dhabi.

The Times quoted people in- volved in the negotiations that the sale was worth $200 million, but Prince will receive payments into the future depending on the company’s financial performance.

A lead investor is Jason De Yonker of Forte Capital Advisors, who helped Mr Prince develop a business plan after he founded the company in 1997, and negotiated its first training contracts.
