Tommy Gahan, the Long Island native who helped build Deutsche Bank’s securities business in the US, has joined media-focused Providence Equity Partners to run its new capital markets division.

Gahan will spearhead a new group within the private-equity firm that will invest in the debt of media, entertainment, communications and entertainment companies worldwide.

The Post reported on the move in May.

Gahan, 46, left Deutsche Bank in March after running its corporate-finance business, including debt and equity underwriting, in the US for almost eight years.

Providence Equity owns stakes in major media companies including Metro-Goldwyn-Mayer, Warner Music and Univision.
