New Delhi, Jul 10: A twitter account, purportedly belonging to terror outfit Indian Mujahideen (IM), has warned that the next target would be Mumbai, prompting the state authorities to tighten security across the city.
A Maharashtra Anti Terrorist Squad (ATS) official said the initial assessment suggests that the account does not appear genuine but the investigators are not taking the matter lightly.
"All the officers of the ATS have been instructed to be alert and city police has been asked to ensure tight security," the official said.
Hours after Sunday's Bodh Gaya serial blasts, a tweet by @IndianMujahidin - which claims to be the IM's official Twitter account - said: "9 Dhamake Humne Karay (We carried out the nine blasts)".
The tweet about Mumbai -dated July 5, two days before the Bihar blasts - reads, "Hamara Agla Target Mumbai Hai. Rock Sago Toh Rock Lo, 7 days Left (Our next target is Mumbai. Stop us if you can. Seven days left)."
