A 27-YEAR-OLD woman was mugged by a persistent robber who kept asking her for more.
The victim was walking through the subway from Springwood under the Castlegate stretch of the ring road when the thief approached from behind at 9.30pm on Saturday.
He said "Don't move", but when she turned around she noticed he was holding a black-handled knife.
He demanded money and she took out her purse and handed some over.
But he said he wanted more. She said she had given him everything, but he kept asking for more money.
She had nothing left and the robber eventually fled.
He was described as Asian, 18 to 25, 5ft 10ins and slim with short black wavy hair. He wore a navy duffel coat and light- coloured trousers.
