Photometric and spectral evolution of the Type Ic supernova SN 2007ru until around 210 days after maximum are presented .
The spectra show broad spectral features due to very high expansion velocity , normally seen in hypernovae .
The photospheric velocity is higher than other normal Type Ic supernovae .
It is lower than SN 1998bw at \sim 8 days after the explosion , but is comparable at later epochs .
The light curve evolution of SN 2007ru indicates a fast rise time of 8 \pm 3 days to B band maximum and post-maximum decline more rapid than other broad-line Type Ic supernovae .
With an absolute V magnitude of -19.06 , SN 2007ru is comparable in brightness with SN 1998bw and lies at the brighter end of the observed Type Ic supernovae .
The ejected mass of ^ { 56 } Ni is estimated to be \sim 0.4 M _ { \odot } .
The fast rise and decline of the light curve and the high expansion velocity suggest that SN 2007ru is an explosion with a high kinetic energy/ejecta mass ratio ( E _ { K } / M _ { ej } ) .
This adds to the diversity of Type Ic supernovae .
Although the early phase spectra are most similar to those of broad-line SN 2003jd , the [ OI ] line profile in the nebular spectrum of SN 2007ru shows the singly-peaked profile , in contrast to the doubly-peaked profile in SN 2003jd .
The singly-peaked profile , together with the high luminosity and the high expansion velocity , may suggest that SN 2007ru could be an aspherical explosion viewed from the polar direction .
Estimated oxygen abundance 12 + log ( O/H ) of \sim 8.8 indicates that SN 2007ru occurred in a region with nearly solar metallicity .
