A teenager threatened to stab a child at a shopping centre as he demanded his bag and cash at knifepoint.
Police have issued CCTV images of a youth who may possess information about the ordeal after the victim was confronted in a city centre mall by a teen on August 5.
A 14-year-old boy was arrested in connection with the incident at Bullring & Grand Central shopping centre in Birmingham last month, reports Birmingham Live.
However, police are also keen to speak to a youth pictured on CCTV, who was wearing a large silver medallion.
In a statement, West Midlands Police said: "The victim ran off to the aid of a passer-by and the offender, who was with another teenager, made off from the scene.
"We’ve arrested a 14-year-old boy in connection with the incident but really need to identify this lad.
"It happened on August 5 at around 5.20pm.
"If you believe you recognise the lad, who appears to be wearing a large silver medallion, please do the right thing and get in touch."
