Fasih Mohammed, the key accused in the Delhi and Bangalore bomb blasts, was arrested at the Indira Gandhi International Airport, Delhi on Monday after being deported from Saudi Arabia.

Fasih (28) is suspected to be a member of the banned terrorist group- Indian Mujahideen and was under detention in Saudi Arabia for five months before being deported to India.

According to reports, India has been requesting the Saudi Arabia government for his deportation alleging his involvement in various terror attacks including the one at Delhi Jama Mashid, Delhi and the blast in Chinnaswamy stadium, Bangalore.

The Saudi authorities gave the approval for deportation after the Interpol issued red corner notice against him on the request of Central Bureau Investigation (CBI).

It is reported that Fasih's wife, Nikhat Parveen, had earlier filed an appeal in the Supreme Court seeking information of his whereabouts, complaining that her husband was detained by the central security agencies, which the Indian government denied.

Fasih's name cropped up after the Indian Mujahideen suspects arrested over the last few months revealed during interrogation.

Bangalore Police will also seek the custody of Fasih, who is believed to be involved in the Chinnaswamy stadium blast two years ago.

"If Delhi Police has taken Fasih into custody, we will also be seeking his custody as he is involved in the Chinnaswamy Stadium blasts", CNN IBN quoted Joint Commissioner of Police (Crime) B Dayanand as saying.

"We have not received any official communication yet. So I can't comment on that but we have already moved a red corner notice so whenever he is deported or arrested, we will seek his custody," he added.
