A newly reported case has raised concerns that a serial sex attacker who targeted victims on the London Underground could have been caught seven years earlier, had police successfully connected three separate sexual assault investigations that took place within months of one another. The failure to link these cases meant the offender was able to continue attacking victims on the Tube network for years before eventually being identified and stopped, raising questions about how police cross-reference and investigate patterns in sexual offences reported across different cases.

The article's full details on the specific investigations, the identity of the attacker, and the timeline of events were not available in the text provided, limiting the extent of this summary. The core claim is that earlier intervention was possible, and that missed connections between the three assault cases represent a significant policing failure with serious consequences for the additional victims affected during the extended period the attacker remained free.
