You haven't mentioned the State you belong to. Neverthless, if you haven't  attended the College and you have been detained, first things first, you wont be sent to the next year. You cannot join another college in the middle of an academic year. You will have to wait until the next year, appear for entrance exam or the admission process whichever is applicable and secure a seat. Now regarding the scholarship, you get scholarship because you are attending college. Your attendance will be monitored. If you don't attend college and if you have been detained, when it goes on the records, it is unlikely that  you will be eligible for scholarship again.

Hi

Don't worry you can join in other college but you need to clear your tuition fee because college management will not provide you certificates until you clear your fee and you have two options you can take your certificates and join in other college after clearing fee or you can rejoin in your college but you will study with your Juniors and you no need to pay fee and coming to scholarship it completely depends on which state you belongs to and if you belong to andhra pradhesh state you will not get any schlorship as per telengana you will get scholarship form government no worries but you need to complete some formalities but only for 2years you get scholarship form government and you will not get scholarship for the year you have detained for many details you can ask in your college they will help you better

Hope this information is helpful

All the best
