Two knives believed to be linked to the death of Fahad Mohammed Nur have been found among trees in Cardiff Civic Centre.
The knives were found by two young boys searching for squirrels in a small wooded area between Museum Avenue and Park Place.
Detectives believe they may be the weapons used during the incident and forensic tests are being carried out to in order to confirm their involvement.
Fahad, 18, died after being stabbed in the lane near Cathays Railway Station just before 0.24am on Sunday, June 2.
Three people have been charged with murder and detectives are not looking for anyone else in connection with Fahad’s death.
Detective Chief Inspector Mark O’Shea, from the South Wales Police Major Crime Investigation Team, said: “The area in and around Park Place was extensively searched following Fahad’s tragic death on June 2.
“At around 6.30pm on the evening of the Pink concert at the Principality Stadium – Thursday, June 20 – a woman reported that her young sons had found two knives concealed within some trees.
“We are very grateful for their vigilance in reporting this discovery but unfortunately her details were not taken at the time, and we ask that she make contact with us.”
If you are that woman, or you think that you know her, please call South Wales Police on 101 or Crimestoppers on 0800 555 111 quoting reference *198071. Alternatively, please attend your nearest police station.
