A number of young men arrested after an incident at Runshaw College in Leyland have now been bailed.
Lancashire Police said that at around 4pm on Monday March 4 a group of young men confronted a rival group in relation to a prearranged fight.
Around 12 people arrived in cars including a Volkswagen Polo, a Vauxhall Astra and a Nissan Micra.
They walked towards the Worden Park side of the Leyland Runshaw College campus shouting at and confronting students. Some of the group had weapons.
A 17-year-old boy received a cut to his arm during the incident and was taken to Chorley Hospital. His injury is not thought to be serious.
No one else was injured during the disorder.
A number of people were later arrested with weapons including a machete, crow bar and knives recovered by officers.
Two men aged 18, both from Preston, an 18-year-old man from Kirkham and three 17-year-old boys from Preston were arrested on suspicion of public order offences.
