The detection of five new fast radio bursts (FRBs) found in the High TimeResolution Universe high latitude survey is presented. The rate implied is6$^{+4}_{-3}\times~10^3$ (95%) FRBs sky$^{-1}$ day$^{-1}$ above a fluence ofbetween 0.13 and 5.9 Jy ms for FRBs between 0.128 and 262 ms in duration. Oneof these FRBs has a clear two-component profile, each component is similar tothe known population of single component FRBs and are separated by 2.4(4) ms.All the FRB components appear to be unresolved following deconvolution with ascattering tail and accounting for intra-channel smearing. The two-componentFRB also has the highest dispersion measure (1629 pc cm$^{-3}$) of any FRBto-date. Many of the proposed models to explain FRBs use a single high energyevent involving compact objects (such as neutron star mergers) and thereforecannot easily explain a two-component FRB. Models that are based on extremeversions of flaring, pulsing or orbital events however could produce multiplecomponent profiles. The compatibility of these models and the FRB rate impliedby these detections is discussed.
