Strangeways was designed by Alfred Waterhouse and cost £170,000 ($207,910) to build. The prison, famed for its prominent ventilation tower and imposing design, has become a local landmark.

A beggar who lay at the side of a road pretending he had no legs was moved on by police who made him stand up and walk away. The man lay slumped on his front in Chengdu, in Sichuan Province, China, with his legs tucked under him, and his jeans stretched out to make it appear he had no legs. He is approached by a police officer, who bends down and talks to him for some moments. The officer then reaches out and helps the man to his feet before guiding him across the road. Chengdu is one of a number of cities where officials have tried to clamp down on begging. (Photo by Rex Features)
