Three police officers were murdered in Shepherds Bush on Friday 12th August 1966 by Harry Roberts and two others. After the killing they went on the run and a huge manhunt ensued. One assailant was captured within hours, the second was found 4 days later in Glasgow but Roberts hid in Thorley Wood near Bishop Stortford and used his army training to survive for three months until he was finally arrested. The notion that someone had killed several policemen shocked the public and attracted a lot of press attention. As the act of murder happened six months after the death penalty had been suspended, many people called for it's return. Two of the assailants died in prison but the gunman, Harry Roberts was released after spending 48 years behind bars. (thetvdb.com)
