During solar flares and coronal mass ejections, free magnetic energy, previously stored within the magnetic field, is released and used to accelerate particles and heat the surrounding plasma. Using multiwavelength observations from AIA onboard SDO, combined with X-ray observations from RHESSI and radio observations from the Nancay Radioheliograph we investigate sources of particle acceleration and heating within the flare-CME system of an event which occurred on the 14 August 2010. This was the first proton event in more than three years. In addition, radio spectrogram data show Type III radio bursts associated with the impulsive/launch phase of the CME, indicating the location of energetic electrons as they escape into the interplanetary medium. A Type II radio burst is also observed as electrons are accelerated in a CME driven shock as the ejected material propagates away from the Sun.
