LONDON (Reuters) - Gibraltar police said they have arrested the captain and chief officer of the detained Iranian Grace 1 supertanker accused of violating EU sanctions on Syria and have seized documents and electronic devices from the vessel.
Last week British Royal Marines boarded the tanker off Gibraltar and seized it on suspicion that it was breaking EU sanctions by taking oil to Syria.
"The investigation is still ongoing and the Grace 1 continues detained," police said in a statement on Thursday.
