Two persons have been detained here for questioning in connection with the e-mail purportedly sent by terror outfit Indian Mujahideen, owning up the attacks outside Jama Masjid in Delhi, police said on Tuesday.

The e-mail was sent using a mobile phone. The SIM card as well as the phone were purchased using a fake address and name, from Mumbai. When Maharashtra ATS and crime branch officers reached the address, they did not find anyone by that name living there, said a senior police official. Two persons have picked up for questioning, he said, refusing to divulge further details.
