More than 100 suspected soccer yobs have been questioned over disorder in Newcastle city centre after the Tyne-Wear derby.
The milestone was reached this week when police made four more planned arrests.
The suspects were taken into police custody to be questioned over the violent disturbance, which erupted after Newcastle United were defeated by Sunderland, in April.
A large-scale police investigation was launched the next day to identify all those involved.
This week’s arrests bought the total number of people questioned to 102 but officers still hope to make even more arrests.
Northumbria Police’s Newcastle area commander, Chief Supt Gary Calvert, said: “This is still very much an active investigation and we continue to receive information from the public.
“I’d like to thank the public again for their continued help in providing information to us about those involved in the disturbance.”
The shocking riots followed the lunchtime game at St James’ Park, on April 14, which saw Newcastle United suffer a 3-0 defeat to Sunderland.
Newcastle supporters clashed with police at Strawberry Place, near the ground, before moving on to nearby St James’ Boulevard, Westgate Road, the Centre for Life and Central Station, following the route Sunderland supporters would have taken.
Police arrested 29 people on the day and the following day a large scale investigation was launched, headed by Det Chief Insp Ged Noble.
Much of the violence was caught on camera, either by police, CCTV, businesses’ security cameras, the media, or members of the public with mobiles.
Detectives have trawled through thousands of hours of footage to identify the people they want to question.
The people arrested are those detectives suspect were actively involved in the disorder.
Det Chief Insp Noble said: “They are the ones that have done something significantly violent in one of the locations where disorder occurred or have been present in all the locations.
“That showed a determination by these individuals to get involved in serious or significant disorder.”
Images of the suspects were initially circulated internally among police to see if they recognised anyone caught on camera.
The faces of those not known to officers were then made public.
Anyone with any information about those involved should call Northumbria Police on 101 ext 69191, or the independent charity Crimestoppers on 0800 555 111.
