Statement from Met Police.
A man has been arrested in connection with an ongoing investigation into the stabbing of a journalist in Queensmere Road, Wimbledon last year.
Officers from the Met’s Counter Terrorism Command, which is leading the investigation into the assault, arrested a 40-year-old man at an address in Cricklewood, London on Tuesday, 7 January. The man was arrested on suspicion of conspiracy to commit grievous bodily harm and was taken to a west London police station, before being released on bail to a date in April pending further enquiries. Officers also carried out searches at four premises in the Cricklewood and Finchley areas and enquiries continue.
The arrest is linked to the ongoing investigation into the assault which took place on 29 March, 2024. Two Romanian nationals were previously arrested upon their arrival into the UK following their extradition from Romania on 17 December, 2024.
Nandito Badea, 20 and George Stana, 24 were both charged with wounding and wounding with intent to cause grievous bodily harm and appeared at Westminster Magistrates’ Court on 18 December, 2024, where they were both remanded in custody to appear at the Old Bailey on 17 January.
