Israeli police issued a request on Tuesday for assistance in locating IDF soldier David Menahem Gordon, 21, who was last seen at an army base’s medical facility at the beginning of the week.

Gordon, a lone soldier originally from the US, was last seen at around midday in the Medical Corps facility in the Tzrifin army base outside Rishon Lezion.

Police said there was particular concern because Gordon, who served with the Givati infantry unit in Gaza during Operation Protective Edge, is an exemplary soldier who did not have any disciplinary issues.

“As far as we know from investigations so far he arrived at Tzrifin two days ago for dental treatment, received the treatment, then left the medical corps, and since then his trail has vanished,” police said according to a report from Walla news.

The missing soldier, as described by police, is 1.70 meters tall (about 5 ft 7 in), has brown eyes and black cropped hair. He was wearing an IDF uniform and a purple beret, and carrying a Micro Tavor assault rifle and a large blue and black backpack. Police said the soldier has an American accent.

According to his Facebook profile, he lives in Tel Aviv.

Police request that anyone with information concerning Gordon’s whereabouts should contact the 100 emergency hotline or call 08-9279244.
