The brother of a 20-year-old woman who went missing on Crete in February turned himself in to police in Rethymno yesterday and allegedly admitted that he had kidnapped a lecturer from Manchester University in England who was holidaying on the island because he thought the academic had information about his sister’s disappearance. Police said that the 40-year-old brother of student Angeliki Stavroulaki told them he abducted the unnamed lecturer, who was friends with his sister. The 50-year-old academic had been on holiday in Lasithi when he was abducted last Thursday. Four more people, two men and two women, are being sought in connection to his kidnapping. The victim has been found but officers said that he had been tortured physically and mentally by his captors, who hid him in abandoned buildings near Iraklio during his ordeal. Stavroulaki went missing after leaving her home earlier this year.
