A Polembros Shipping subsidiary is looking to recoup $12.3m seized by the US government after a suezmax it sold ended up in Iranian hands.

Crystal Holdings has filed papers in US federal court placing a claim on nearly $10m in funds held at Wells Fargo bank and another $2.3m of its own money frozen two years ago over the sale of the 150,800-dwt Rima (ex-Nautic, built 1998) to alleged Iranian front company Taif Mining Services.
