A ship connected to ArcelorMittal has reportedly been detained in Gibraltar after a bunker fuel spill.

The 93,200-dwt bulker AM Ghent (built 2011) spilt about 1,000 litres of fuel in the early hours of 12 February, the Gibraltar Chronicle reported on Monday, with the ship now being held by authorities there.

"All cost attributed to this incident will be recovered from the vessel and until such time that payment is received the vessel will remain detained in [British Gibraltar Territorial Waters]," the Gibraltar government said on Monday.
