Police are appealing for social media users to come forward with information about the fight in Reigate town centre that took place on Monday 8 June.
Since the incident, which occurred at around 4.45pm that day, officers have made a number of enquiries, including as regards social media, and now believe several local Twitter users may be able to assist with their investigation.
Investigating Officer PC Katherine Peters said:
“As part of our investigation we have noticed a number of people talking about the events of that afternoon on social media. In particular, people have mentioned close encounters with items thrown during the altercation.
Social media is an excellent investigative tool which we embrace, but it can bring challenges when we need to contact people so I would appeal to those people using #Reigate who have spoken about this case online and who may be able to assist our investigation to contact officers as a matter of urgency.”
Five men aged in their late teens and early 20s were arrested in connection with the incident. They were released on police bail until Thursday 3 September while the investigation continues.
No serious injuries were reported and it is believed all those involved in the incident are known to each other.
