Violence has erupted as fans clashed with police following Sunderland's 3-0 win over Newcastle at St James' Park on Sunday.
There were chaotic scenes in Newcastle city centre as disgruntled fans set bins on fire and threw bottles, bricks and firecrackers at police officers mounted on horses.
Riot police were called to the scene in an attempt to move the large crowds back to allow supporters safe access to transport services.
Northumbria Police have confirmed that 29 arrests were made during and after the game while three police officers were also injured during the trouble, with one requiring hospital treatment.
They released the following statement on Sunday evening: "The most serious incident involved a group of Newcastle fans in Central Station attempting to confront Sunderland supporters, but they were intercepted by officers from British Transport Police.
"During this incident missiles were thrown at the officers, which resulted in three injuries to officers - one of them requiring assessment at hospital.
"The vast majority of fans were well behaved today and enjoyed the Tyne-Wear derby for the great occasion that it is.
"Disappointingly, there was some disorder involving what appear to be Newcastle United supporters following the match in the city centre, including an incident at Central Station.
"Disruptive behaviour of any kind is not tolerated. Inquiries will take place into these incidents and action will be taken against all those involved."
The game itself saw Sunderland record their first win at the home of the bitter rivals for 13 years.
