Delhi Police — traffic police challan for offence I have not done

Hi,
Challan No.
I was going to Red Temple with my wife and 5 year old son on 17th June 19 on 2 wheeler. I crossed red light mistakenly(behind a vehicle so not seen the light crossed with it) at IP Marg under flyover while taking turn to right. A traffic police constable asked to stop me so I stopped. He said you have crossed red light so it will be a penalty for this. I said, 'ok do the challan'. He said Rs 1100, I said challan amount is Rs 100 for this offence mentioned on your website and I don't have this much amount. He said don't show me this and pay 1100. I went to search ATM crossed the road full of traffic with my son which is very naughty left my wife behind with the bike.They kept my DL I paid them 1100 and got challan, when I saw the challan they do it was also for zigzag and dangerous driving. How can I do the same with my family on bike and how can a officer can do the challan for the offence I have not done.
