Magistrates heard that Laura Ghodsiam, 59, was resting on a bench near a bus stop in Belsize Park, north London, at around 9.30pm on November 5 when the pair grabbed the iPhone. Valerie Benjamin, prosecuting, told the court: "While sitting there she began checking her emails on her phone when she noticed a hand reach over her and take it. Two police officers were walking nearby and noticed the victim shouting. They ran to join in the chase. As the officers pursued the teenagers, they radioed for support, attracting the help of DC Cashman and a colleague, who were in a police car nearby. However, while running after the youths, DC Cashman collapsed to the ground. She was taken by ambulance to the Royal Free Hospital but died about an hour later. Dressed casually in jeans, the two teenagers stood with their hands in their pockets as they pleaded guilty in court on Wednesday. One of the pair apologised to the magistrates, saying: "I would like to say I am sorry for committing a crime. Passing sentence, Paul Brenells, chairman of the bench, said: "You are both going to end up in serious trouble if you continue on this path. A post-mortem examination of DC Cashman proved inconclusive and the cause of her death has not yet been determined. Tributes were paid to the popular officer, with Metropolitan Police Commissioner Bernard Hogan-Howe describing her death as a "terrible loss to everybody who knew her." He added: "Adele was an eager officer, she was in a crime squad, she was out there chasing criminals, which is I'm sure the reason she joined. She was out there being brave, getting stuck in and then this great tragedy has happened.
