This is quite a specific question. Legally, I have no idea.
But it’s fair to say that if the person is ruled innocent, I don’t think he would be stopped from any government job.
To your question, if the police officer is proven innocent and his profile stands clean, he should very certainly get his same job back. But then I am sure a lot of factors might come into play here. For example, his age. After a certain stage, he might not get appointed back to his position. To that, since lagging the experience, he might not necessarily be qualified for the promotion.
But then the bottom line is that if the person was wrongly jailed and he now has a clean slate in front of the court of law, he should get back the same job with full honour.

However, in case, if he is convicted and rightly jailed, he won’t be allowed back in his job even when he has served the complete sentence.
In fact, per government regulations, if a person has spent more than 48 hours in police custody, he or she would be barred from government employment.
In our country, it’s quite difficult for individuals with bad police record to re-join the society and live a normal life. They are shunned by everyone. They don’t find employment. These eventually lead them to either other crimes or suicide. Instead of out-casting them, these people should go through proper rehabilitation and supported to be back in society.
All said, the answer to your question, even though I am not legally sure, is YES.
