Ji Zhongxing, a motorcycle taxi driver from Heze city, Shandong province, was paralysed from waist below after receiving beating at the hands of police in 2005.
He first attempted to distribute fliers to highlight his grievance near the arrival lounge of the airport last evening before setting off the homemade explosives causing serious injuries to his arm.
Some reports say his left arm has been amputated.
The Beijing News newspaper on Sunday quoted several witnesses as saying Ji repeatedly yelled "I have a bomb, stay away from me" before the bomb was detonated.
