Officers identified Khadir through intensive CCTV footage, financial tracking and local resident checks carried out between Christmas and New Year's Day.
Investigators located his address and worked with firearms command to secure arrest warrants.
On 2 January, police arrested Khadir and seized the replica gun used in the attack, along with fake ammunition and matching clothing.

Cross also praised the victim for coming forward, calling it "incredibly brave" and noting his identification of Khadir as a crucial step in the investigation.
