Detectives believe Issa Ponda may have inspired the attack on Katie Gee and Kirstie Trup, who remained in hospital being treated for their injuries last night.
Sheikh Ponda surrendered a day after he was injured during police attempts to arrest him on the orders of Tanzania's chief prosecutor.
He is under guard being treated in hospital and will be interrogated once doctors discharge him.
Miss Gee and Miss Trup, both 18 and from north London, were volunteering for at a Zanzibar nursery school when two men on a moped threw acid over them, wounding them on their faces, hands, legs, backs, necks and chests.
Both are said to be "devastated" by the extent of their injuries, which relatives fear will leave them with long-term physical and mental scars. » | Mike Pflanz, Stone Town, and Victoria Ward | Sunday, August 11, 2013
