Save the Children promises review after claims against former CEO

UNICEF Deputy Executive Director Justin Forsyth speaks during a UNICEF media briefing in September 6, 2016.

(CNN)Save the Children has apologized for the past inappropriate behavior of its former chief executive towards female staff, promising a fresh review into the charity's "organizational culture."

In a statement Tuesday, the international charity said former CEO Justin Forsyth was investigated twice after complaints from three women about his conduct in 2011 and 2015.
On both occasions, the investigation led to "unreserved" apology from the chief executive and "the matters were closed," the statement said.
    The Save the Children allegations follow outrage over revelations that staff from British-based charity Oxfam abused their position of trust to engage in sexual acts with the people they were supposed to be helping.
    According to the BBC, which first reported the claims, Forsyth allegedly sent inappropriate text messages to young female staff about what they were wearing and how he felt about them.
    Forsyth left the charity at the end of January 2016 to take up a role as the deputy executive director at UNICEF.
    He's reported to have issued a separate statement Tuesday, saying he had made some "personal mistakes" during his time at Save the Children, and that he had thought "the issue closed many years ago."
    "I recognize that on a few occasions I had unsuitable and thoughtless conversations with colleagues, which I now know caused offense and hurt," he said, according to the BBC.
