Luis Grijalba, a 43-year-old druglord wanted in the US for exporting cocaine, was arrested in the UK after his wife's social media posts revealed their location. He had survived two assassination attempts and was monitored by the DEA through his wife's extravagant travels. The NCA confirmed his arrest near London Bridge and extradition proceedings are ongoing. This case highlights the pervasive reach of social media and how it can be used to track down criminals evading justice.
