Other locations have included the court house, a disused office block, Evershed House, and St Peter's Church, all in St Albans, an abandoned mental facility in Worthing, and a wedding dress shop in Muswell Hill, north London. A week of episodes in 2011 saw filming take place on a beach in Thorpe Bay and a pier in Southend-on-Sea—during which a stuntman was injured when a gust of wind threw him off balance and he fell onto rocks— with other scenes filmed on the Essex coast. In 2012, filming took place in Keynsham, Somerset. In January 2013, on-location filming at Grahame Park in Colindale, north London, was interrupted by at least seven youths who threw a firework at the set and threatened to cut members of the crew. In October 2013, scenes were filmed on a road near London Southend Airport in Essex.
