Mumbai, Apr 26 (Agencies): A suspected Indian Mujahiddeen (IM) operative wanted by Maharashtra, Karnataka and Gujarat Police forces for various acts of terror -- among these the July 2011 triple blasts of Mumbai -- was arrested from the airport here on Tuesday, a senior police officer said.

ATS sources said the accused, Zainul Abedin, was picked up from the Mumbai airport. The twelfth person to be arrested in the case, he was earlier detained in Saudi Arabia in 2015.

"We arrested one Zainul Abedin, a suspected IM terrorist, from the airport this morning. We produced him in the court and got his remand for ten days," a senior Anti-Terrorism Squad (ATS) official said.

"We will be questioning him in connection with the 2011 Mumbai serial blasts case," he said.

The accused was allegedly involved in supplying the explosives used in the Mumbai triple blasts. The bombings were executed by Yasin Bhatkal, who also planted one of the explosives.

Abedin, hailing from Bhatkal, is allegedly close to IM operative Riyaz Bhatkal – who operates from Pakistan. Sources said his name came up during the questioning of an accused from Karnataka, who was arrested by the ATS last year.

A red corner (RC) notice was issued against the accused, based on which the ATS sleuths of Kalachowki unit arrested him, police said.

According to police, Abedin was allegedly responsible for supplying explosives for operations of the banned outfit.

A mixture of trinitrotoluene, ammonium nitrate and petroleum carbon oil was used to prepare four bombs that were set off at Zaveri Bazaar, Opera House and Dadar between 6.52 pm and 7.05 pm.
Though a fourth bomb was planted at the Dadar Phool Market under a police van, it did not go off.

The bombs were assembled in a rented room at Habib Mansion in Byculla. As many as 27 people were killed and another 127 injured in the three blasts.
