POLICE and paramedics were called to the Tesco Express petrol station in Hungerdown Lane shortly after 6pm on Sunday following a report that a 15-year-old boy needed medical care.

It is believed an altercation happened outside the shop, which led to the boy being assaulted. He was taken to Bristol Children’s Hospital where he remains this morning, and is said to be in a serious but stable condition.

A 23-year-old man was arrested on suspicion of GBH and taken to Melksham custody for questioning.

Police have issued an appeal for witnesses - call 101 or Crimestoppers on 0800 555 111.

Inspector Mark Luffman said: “Understandably, there was a lot of concern from the community, especially on social media, and I am aware that the large number of police and other emergency vehicles at the scene would have no doubt been unsettling for local people.

“However, it is really important to stress that any speculation about the circumstances of this incident is really unhelpful and can negatively impact on a police investigation. Although we are at the early stages of our investigation, we can confirm that no weapons were used during the assault.

“We have spoken to a number of witnesses already, but if you believe you witnessed anything that may help our enquiries, and you haven’t already spoken to police, please get in touch via 101 and quote crime reference number 54190023966.”
