Wow, this came out of nowhere! Prof. Deepak Pental (a professor of genetic engineering at the Delhi University, and also its Vice Chancellor during 2005-1010) was arrested, sent to Tihar Jail, before he got bail later in the evening. The charges against him were filed by a fellow DU professor (but in a different department), and they include forgery, illegal transport of genetically modified material, and plagiarism. For some strange reason, most news outlets have played up the plagiarism angle; the other charges appear far more grave (one of them, apparently, is so serious that one can be sent to jail for life).
Most news stories I have seen today were short on details, since they were reacting to fast-changing events of yesterday. Only a few have managed to go beyond the bare-bones version put out by PTI. Here are the links to some of the better-reported stories: The Telegraph, India Today, and here.
I'm sure we will get a lot more details in the days to come.

Update: The NDTV debate doesn't offer details, but the comments by K.L. Chopra (from the Society for Scientific Values) are quite damaging to Pental's case.
