The 16-year-old male was arrested on suspicion of murder on Monday, 27 December – he remains in custody at a south London police station.
An investigation was launched after police were called to London Road, close to West Croydon Railway Station, at 6.41pm on Thursday, 18 November to reports of a fight involving a number of people.
Shortly after 7pm police attended a south London hospital after a 14-year-old boy self-presented with stab wounds.
Despite the efforts of doctors at the hospital, the boy died a short time later.
The boy was later formally identified as 14-year-old Jermaine Cools. A post-mortem examination gave Jermaine’s cause of death as multiple stab wounds.
