Detective Chief Inspector Elizabeth Pirie said: “Whilst the two arrests are a significant development in our investigation, which has moved at pace since the incident was first reported to us, we still urge our communities to contact us with any information, no matter how small it may seem.
“I understand the effect that such an incident will have had on the local community, and I do not underestimate the disruption that our scenes have caused to those living in the area. We are working hard to reduce the impact.
“We are extremely grateful for the understanding of our communities whilst we continue working to establish the full circumstances surrounding this incident.”
The force said it was interested in speaking to anyone who attended the party or has footage, including doorbell camera footage, covering Park Road and the surrounding area.
Anyone with information should contact police on 101 or via their website, quoting reference 44260534624, or Crimestoppers by calling 0800 555 111 or using its website.
