Brothers of a deceased Jordanian policeman have called on authorities to release details regarding the circumstances of his death, amid claims their relative was drowned. Last week policeman Ibrahim al-Jarrah, aged 27, had been accompanying Israeli tourists to the Ma’in hot springs, close to the Dead Sea, shortly before he was found dead at the site. Al-Jarrah’s brother, Joseph, told Arabstoday: “We want a full explanation of the death of our brother, who remained in sulphuric water for 40 hours.” Relatives have claimed al-Jarrah was killed by criminals. Security sources have meanwhile denied reports of foul play circulating on social networking sites, amid claims al-Jarrah was killed after receiving a blow to the head while escorting 21 Israeli tourists to Ma’in. “There is no criminal suspicion here,” sources told Arabstoday.
