It represents a light so basically, it has similar features same as light and not more than the light can travel at 3x10^8 m/s. And also, particle must have mass enough to produce a certain amount of attracting force as it travels way beyond the speed of light. An object increases its mass as it travels a huge amount of speed say for example greater than light. Thus if it increases its mass then the force of attraction between anybody and that certain body increases.

The flaw here is that gravity does not involve only mass but also energy. In this way, photons are sensitive to gravity as well.
I guess I answered everywhere by now :)
Thanks for taking the time to clarify things!
It is always a pleasure! :)
