Should I quit my job after being suspended pending investigation thats not yet been concluded?

The citizens advice bureau is usually a good option before paying out for more expert advice.

On a 0 hours contract,  all they had to do was not offer you any more shifts.   But theyve terminated you with immediate effect, and that makes me wonder if theyve given you an opening? 

Even as 0 hours you do have certain rights, if youve been doing a regular number of shifts for a long time, its not unreasonable to expect that to continue or to have had your contract updated.

Update: my employer has updated the rota and looks like they’ll be paying me for at least two shifts a week until they come to a conclusion I guess. Thats one positive in this situation.

Thats better news.  If nothing else it will give you a breathing space, to look around for something better, and get some advice.
