As I could ascertain Section 70b of the Hyderabad Police Act states as follows:
70: Indecent acts in street etc.
Whoever in any street or public place or place of public resort (a) is in such a state of intoxication as not to be able to protect himself, (b) behaves in an indecent, riotous disorderly manner, (c) uses any threatening, insulting or obscene words or gestures, likely to disturb public peace or cause public nuisance, shall be punished with imprisonment for a term which may extend to eight days or with fine which may extend to fifty rupees
The matter is a petty offence and generally courts dispose of such cases on imposition of fine, once the accused pleads guilty. It is not necessary that the accused be present in the Court; an advocate could be authorised to represent him.
Once your friend receives the summons from the court, he may ascertain whether such a practice in in vogue in that court and, if so, he can plead guilty and get the matter closed.
The offence alleged does not involve moral turpitude and hence need not affect his prospects for public employment. However, he need to make a honest disclosure the information, as sought in the attestation form. (Every person, once selected for public appointment need to furnish such a form in the prescribed format).
