Thanks Kevin your feedback is much appreciated.
Well what has freaked me out is the way it was done. As stated I was given a slip and asked to wait and the slip said that I am being held for "further checks". The guy did say that since my brp is new it needs checking and he asked atleast 3 times if I had an '"immigration issue".
So far all my visas have been granted (by the grace of Lord Shiva) but he asked two times if my PSW permit was curtailed which isnt true. I was so freaked out that I asked him why is he checking me to which he replied "errr obviously you dont have a British passport and not a regular resident". He was Sikh I guess and continued to do small talk with me.
I am worried if this will happen again. He did stamp my passport but the incident has really upset me. Maybe as a girl I panic 24/7.
Why did he ask about my PSW visa which was expired as 2 yrs ago I made an entry clearance application via Tier 2. My company did have licence issues which were resolved in 2013 and my extents ion was done with no issues. Ever since the licence issue I check the registers of sponsors everyday.

. Wondering if they had a record of the licence issue and hence the questioning regarding "immigration issues". When I asked my employers they obviously said that its nothing to do with them.
After this has happened I am scared to travel or maybe paranoid. I have holidays planned in Europe and my upcoming wedding to my boyfriend (which will take place in India) and do not want to be embarrassed again. Does it help to do a registry in the UK before going to India to marry? I should be able to utilise my tier 2 right?
