A pro-ISIS Twitter account has given a call for "car bomb" attack when US President Barack Obama visits India next week.

"Heard that enemy of ALLAH, obama is coming india soon. And indian muslims are good in chemicals, so a chemical car bomb will be good idea," said a tweet by @magnetgas, put out January 19.

This is the same Twitter account that earlier claimed that Saheem Tanki, a Thane youth who joined the Islamic State of Syria and Iraq, had died in a suicide bombing mission in Syria.

The National Investigation Agency (NIA) suspects that the account is run by one of the four Thane youth who joined ISIS, reported The Indian Express.

The four were Amman Tandel, Fahad Sheikh, Areeb Majeed and Saheem Tanki. While Areeb is back in India and is in a jail and Tanki presumed dead, either Fahad or Amman could be operating the account.

Magnet Gas has 293 followers and has so far sent out 533 tweets. The user uses the nom de guerre 'Abu______al Hindi al baghdadi al shami', leaving out the part that identifies him. His location according to Twitter is Turkey.

Tanki's nom de guerre was 'Abu Uthman Al hindi'. It is not known what names Fahad or Amman are using.

An NIA source told the newspaper that they had taken note of the threatening tweet and said "a close watch is being kept on the Twitter handle. As it is believed to be operated by one youths from Thane who joined the IS."

The source said US authorities would be approached for details of the handle.

Obama arrives in India on January 25 and will be the chief guest at the Republic Day parade the next day.

Earlier, police arrested Mehdi Masroor Biswas, a youth working in Bangalore, for running Shami Witness (@shamiwitness) , another pro-ISIS Twitter account.
