A founder of Texas-based private equity firm Delos Shipping has launched a scathing attack on his partner Brian Ladin, calling him a “scam artist” who has diverted millions of dollars from the venture for his own purposes.

The explosive charges come in a Texas state court lawsuit filed by Richard Squires, who co-founded Delos with Ladin but now seeks to recoup some $4m he alleges Ladin diverted from the company to fund his own lavish lifestyle.
