Four men and a boy were arrested on Wednesday morning on suspicion of violent disorder.
The sixth person, a boy aged 17, from Watford, was arrested at Hatfield police station on Friday.

A 17-year-old boy from Croxley Green was the fifth person held.
They are all subject to a strict bail condition not to attend football matches or be within a mile radius of the town centre four hours before and four hours after a game takes place.
Supt Sue Jameson said: "The disorder took place in a busy road in front of shopkeepers, people going about their daily business and families with children who were on their way to watch the first home game of the season.
