Runshaw College students and bystanders have been asked to send in video footage or pictures of the gang attack at the college.
South Ribble Police have released the appeal, particularly for video footage, after a group of 12 young men arrived at the college in Leyland during Monday (4 March).
Brandishing machetes, crow bars and knives the group were there for a ‘pre-arranged fight’ according to police.
A 17-year-old boy had a cut to his arm during the incident, and was treated at Chorley Hospital.
Six people who were arrested have now been released on bail, with strict conditions attached.
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. All have been bailed with strict conditions to April 2.
Chief Inspector Gary Crowe from South Ribble Police said: “We are continuing to appeal for information following an incident of disorder close to Runshaw College in Leyland.
“We know this disorder was related to a personal issue between two members of each group and officers have acted quickly in making a number of arrests. These individuals have since been bailed but I must stress these are with strict bail conditions.
“A dedicated team of detectives are working on this investigation and as part of their enquiries are appealing for information from witnesses, particularly those with video or mobile phone footage.
“We are aware a number of videos circulating on social media, but it is crucial to our investigation this footage is provided to police to assist with our enquiries. A number of people have come forward and spoken with police, but I would encourage anyone who has information and has yet to speak to us to get in touch.
“We have increased our patrols in the area and we would like to reassure people a strong police presence will remain in Leyland for the coming days.
