Two teenagers have been charged following a triple stabbing outside Harrow-on-the-Hill station in north-west London, police have confirmed.

The attack happened shortly before 2.40pm on Wednesday, 4 November, outside the busy station, which serves the Metropolitan line and National Rail services. Emergency services were called to the scene and found three people with stab wounds. All three were taken to hospital, where their injuries were assessed as neither life-threatening nor life-changing.

Officers arrested two suspects in connection with the violence. On Friday, 6 November, the Metropolitan Police confirmed that the pair had been charged and were due to appear at Willesden Magistrates' Court later that day.

One of those charged is 18-year-old Kiara Chambers Williams, of St Ann's Road, Harrow, who faces a charge of possession of an offensive weapon. A second teenager was also charged in connection with the incident.

In the aftermath of the stabbing, senior officers brought in temporary stop-and-search powers under Section 60 of the Criminal Justice and Public Order Act 1994 across the London Borough of Harrow. The powers allow officers to stop and search people without reasonable suspicion within a defined area for a limited period, and are used when serious violence has occurred or is feared.

Superintendent Zubin Writer, the Metropolitan Police lead for Harrow, said officers responded within minutes of being alerted and that high-visibility patrols had been stepped up to reassure residents and commuters. He said extra powers had been put in place to allow officers to temporarily stop and search people in the area, and urged anyone with concerns to keep reporting them.

The stabbing happened at one of north-west London's busiest transport interchanges. Harrow-on-the-Hill serves the Metropolitan line and National Rail services, and the area around the station is heavily used by commuters, shoppers and school pupils in the afternoon. Police cordoned off the area while officers searched for the suspects and paramedics treated the injured at the scene before taking them to hospital.

The use of Section 60 powers in the borough formed part of the immediate response. Such authorisations are time-limited and allow officers to search people without reasonable suspicion within a defined area, and they are used after serious violence or where further violence is feared. The Metropolitan Police said high-visibility patrols would continue in the area while enquiries went on.

Detectives are continuing to investigate the circumstances of the attack. Police have appealed for anyone with CCTV, dashcam footage or other information to contact them on 101, quoting reference CAD 3862/04NOV26.

The charges are allegations only. Both teenagers are presumed innocent until proven guilty in court, and reporting restrictions may apply to court proceedings involving young defendants.
