Police investigating the death of a 16-year-old girl are appealing for motorists with dashcam footage to get in touch as they may have filmed the incident.
Wenjing Xu died during an alleged attack in Treorchy, South Wales, on March 5, which also left two men in their 30s with injuries.
Police were called to Baglan Street at around midday on Friday to reports of a stabbing at the Blue Sky takeaway restaurant.
Detectives said the area was busy at the time and motorists may have seen the incident unfold between 11.50am and 12.15pm.
Detective Chief Inspector Mark Lewis, who is leading the investigation, said: “We have a dedicated team of officers who have been carrying out extensive inquiries in the area and I would like to thank all those who have got in touch so far.
“We know that the incident occurred at a very busy time of the day when lots of cars will have driven past the Blue Sky premises which is at the centre of our inquiries, and it is likely that a number of those people will have dashcam footage which may help us.”
A 31-year-old man known to the victim has been arrested on suspicion of murder, and a man aged 38 is also in police custody in connection with the incident.
Both are being treated in hospital for injuries sustained during the incident and are in a stable condition.
Specially trained officers continue to support Wenjing’s family.
Mr Lewis added: “This is an extremely difficult and traumatic time for Wenjing’s family.
“I am aware there is speculation and rumour online, so I would urge people to be respectful, and not fuel that situation.

“We are monitoring open source platforms and anybody who commits offences will be robustly dealt with.”
In a statement released last week, the teenager’s family said: “Wenjing had a very gentle soul, she was a very quiet person. Wenjing helped the whole family, working in the family takeaway.
“She enjoyed school and worked very hard. She was loved by her family.”
