Four riot suspects - including a 15-year-old boy - handed themselves into police last night after more pictures were published in the Telegraph & Argus.
The suspects, aged 15, 17, 22 and 30, were questioned last night and a further four made arrangements to see officers over the weekend.
As revealed in yesterday's T&A, the police have issued photographs of 20 suspects caught on video footage in July.
By 8am last night, the incident room had received 40 calls and officers had received information on all 20 suspects whose pictures were published.
A further 40 pictures are expected to be released within the next two weeks in a final bid to name and shame the rioters.
The photographs will be displayed in police stations, courts and mosques across the district and airports have been alerted.
Anyone with information can call the incident room on (01274) 376915 or the Urdu-speaking line on (01274) 376916.
