Qayamuddin Kapadia, one of the key conspirators of the July 26 serial blasts in the city, has been arrested by the Madhya Pradesh police.

"Qayamuddinn Kapadia has been arrested by the MP police. I do not have much details on this matter as of now," joint commissioner of police of city crime branch, Ashish Bhatia said on Monday.

Qayamuddin, who hails from Vadodara, was declared absconding by the city crime branch investigating the serial blasts cases.

He allegedly planted cycle bombs in the city as well as bombs in different parts of Surat, Bhatia said.

He was also responsible for purchase of cycles on which the bombs were mounted and kept in different parts of the city, he added.

According to crime branch, after the arrest of SIMI leader Safdar Nagori in March this year, the Madhya Pradesh police had come to Vadodara in search of Qayamuddin, but he managed to escape.

Qayamuddin, who is an expert in using explosives, was allegedly present during various SIMI terror training camps in Waghamon in Kerala and Halol near Vadodara and was instrumental in training the participants.

He is also wanted in a stabbing case registered under the Karelibaug police station of Vadodara city.

The accused, who is a rubber stamp vendor, had also stayed in Ahmedabad along with another absconder in the serial blast case, Abdus Subhan alias Tauqeer, prior to the July 26 terror attack, they added.
