George Osborne's aide to be cautioned over bar fracas Mario Pisani, 34, was detained by police following a disturbance at Adventure Bar in Battersea Rise, south west London, in the early hours of November 10. A Crown Prosecution Service spokesman said: "Following a further consideration of this case, under our continuing duty to keep all cases under review ahead of trial, it has been decided that an out of court disposal is the most appropriate way of dealing with this case bearing in mind the nature of the offence and likely penalty. Pisani, from Battersea, south west London, was suspended from his job as a press officer at the Treasury after the incident. He has previously worked in the private office of Alistair Darling, the former Labour chancellor, as well as being a former speechwriter for the current Chancellor. A 28-year-old unnamed woman was cautioned for assault on police in the same incident Pisani was charged over.
