Chennai Phone no. (44) 811 2060
The above phone no. works very well. I used it twice, once 2 weeks back at around 11PM EST and yesteray at 12PM EST, both times they asnwered on first ring, same lady. Ask direct question and she would respond.
Good Luck Everyone !
BTW, it seems Mumbai P IV has asked specifically for 2 PCC\'s one from Regional PP office and another from local Police Station.
