Three people were arrested for public order offences at yesterday's local Plymouth Argyle v Exeter City football derby.
Away supporters were delayed in leaving after disorder broke out near to the ground after the match. A police officer suffered a minor injury.
Police say the match passed 'largely without incident' and that the vast majority of fans were well behaved and in good spirits.
More than 20 people were arrested when the teams met in 2010, when violence broke out in the stands at the Home Park stadium.
