A former Citigroup executive raised $3bn (€2.3bn) for his first US infrastructure fund, amid heightened public concern over private equity investments in the sector.

The fund from Alinda Capital Partners launched in September 2005 and it made its final close last week. It targets a wide range of public sector and energy infrastructure investments. It was oversubscribed and raised three times its initial target. CP Eaton was the placement agency for the fund.
