Information from my Lawyer on PCC (might be slightly stale, however check the last paragraph)
Update from AILA on Police Certificates/India
POLICE RECORD
All Indian IV applicants aged 16 and over, residing in India,
should obtain police certificates from the local Passport
Office. Applicants whose Indian passport was issued within the
past six months may present just the Passport Office Police
Certificate, and need not obtain additional police clearances.
Applicants over age 16, whose passports were issued more than
six months previous to visa application, must also obtain a
police clearance from the
District Police Office serving the applicant\'s place of
residence.
Indian passport holders applying for visas outside India should
obtain a statement from their local embassy or consulate
confirming they have no criminal record. Non-Indian IV
applicants residing in India should obtain police certificates
from the District Police Station serving their area of
residence. Indian police certificates are not available for
foreign (non-Indian) applicants applying outside India.
John Nay, the supervisory Consul General in New Delhi, has
stated that all Indian posts (except Calcutta, which only deals
with orphans) are changing to the new policy effective February
1. Each post will update its own web site, and they are all
including new instructions in their appointment letters. They
are still working out some implementation details, so they ask
for your patience and understanding, but desire to assure
applicants that they will not be "unfairly wiped out on this."
